It’s getting to that time…

What time is that?

What was once deemed the best razor for men is now sitting on your bathroom counter.

Yeah you know the one, it’s the one that is about 20 shaves past its prime.  Blades are clogged with shaving cream and hair.

And most of all, you don’t want to plunk down your hard earned cashed on another damn set of cartridges that are just going to be thrown out in a couple of weeks.

So your thinking perhaps that a electric shaver might be the ideal product for you.  I mean why not?

It lasts on average about 20 years and for the most part provides a pretty quick shave in the morning.

So after doing a bit a research, you may start to get overwhelmed with all the options available to you.

I mean there are just SO many to choose from.

Here’s just a few things to consider when looking them up:

  • Foil vs rotary shaver heads
  • Wet vs dry shaving
  • Self cleaning vs manual cleaning
  • Trimmer attachments vs a separate beard trimmer
  • Sub $100 model vs a $250 model

It gets even worse:

What if you you have sensitive skin?  Personally when I shave I get nasty razor burn on my neck.  Will an electric shaver make it worse or make it more bearable?

Also Have you asked yourself this question before: ‘I have been using a Gillette Mach 3, or some other safety shaver for the past 10 years and I am sick of buying cartridges, is it worth investing in an electric shaver?’

Will it be cheaper than a safety shaver over the long term?

By the end of this guide you will be equipped to pull the trigger on the right electric shaver for you.

You worked hard for your cash, the last thing you need to do is blow your money on some second rate electric shaver that will last you about one year and just start plucking at your hair.

So lets take a look in this in-depth electric shaver guide and discover a few of the mechanics behind electric shavers so you can perhaps arm yourself with great knowledge so you can buy with confidence and most importantly satisfaction.

Foil vs Rotary Shaver: What’s REALLY the Difference?

Why are there two types, and most importantly, what are the advantages?

The low down on a foil headed electric shaver:

These things have been around for years, in fact they on the first electric shavers invented by Jacob Schick in 1923.

A foil head contains oscillating blades (blades moves back and forth).  Think of something similar to a barber’s scissors or a desk fan where it goes back and forth.

With a foil head one of the biggest drawbacks you will come across during your research is how often it is cited that they struggle with the contours of your face when compared to other electric shavers.

The reason for this is since the foil head is more rectangular in nature (like a safety shaver) it can only pivot so much when going across your face.

Granted you can find foil heads from Braun like this one here, that does allow for some limited pivoting, but getting in and around the nose or chin is often sometimes the biggest drawbacks you will hear from folks that use these type of shavers.

You will also find that foil heads are a bit more on the noisy side when compared to their rotary counterpart.

When shaving with a foil headed shaver, technique differs from that of a rotary head.

For a foil head, you should go up to down, or left to right (pretend like a lawn mower going over a football field) as seen in the illustration below:

Foil Razor Shaving Technique

You definitely don’t want to go in a circular motion.  This may take a bit of getting used to if you are coming from a rotary electric shaver, while it might not be that far of a leap if you currently use a safety razor.

One thing that you will see in much of the marketing speak around these types of electric shavers is the mention of microvibrations per minute.  Essentially all that is telling you the higher the rate, the more hair that can get into the foils and be cut.

Great, so now you know some great key takeaways for foil headed trimmers!

Breaking down the rotary headed trimmer:

First off here is what a rotary head trimmer looks like (only one of three discs shown):

Rotary Electric Razor Head

The rotary head has three discs (has been this way since the mid 1960s when it was introduced by Philips).  Since the 1960s rotary electric shavers have come a long long way in terms of looking sleek!

So how does a rotary disc exactly work?  Within these three discs you have the razors that spin around incredibly quick to cut your beard.  Just like how a weed wacker works.

The biggest benefit you will always read about rotary style razors is that they can bend to the contours of your face.

Most rotary heads can pivot 360 and also flex inwards within the middle of all 3 rotating blades to get closer shaves, especially around the nose, chin, and jawline areas.

However to counteract that point, a foil electric shaver will be much smoother and closer shave along the cheeks.  Its all about compromise between these two shavers, hence why consumers have two options.

Unlike the foil headed shavers where you go up and down or side to side (like mowing a football field remember?), the rotary head you want to go in a circular clockwise motion as seen in the illustration below:

Rotary Razor Shaving Technique

If you were to use a rotary head and shave up and down you are going to experience some really nasty pulling of your hair and give you a miserable experience.

Alright great, now you know a bit more about the differences between a foil electric shaver and a rotary electric shaver!

What the #[email protected]& is Wet & Dry?

Alright so now we know a bit more about the different types of shaving heads, now how do we go about deciding how to maximize their use?

You may find while browsing through the shaver types, you have some that are wet & dry, while others make no mention to their functionality, what gives?

So a wet shave isn’t simply just being able to use the shaver in the shower (I know that’s what I originally thought).

I was wrong, what wet actually means is the ability to use the shaver with shaving cream.

So you can slop on some high quality shaving cream like The Art of Shaving Cream and begin going over your face with your electric shaver.

So the whole point of buying an electric shaver was to save money and not worry about buying all the extras that come tacked on with a safety shaver correct?

Well yes of course!  However, if you are like me and have super sensitive skin, an electric shaver that has the capability of shaving ‘wet’ might be a godsend to the skin on your face.

In addition to helping out people like me with sensitive skin, when you actually add the shaving cream to your face, the cream itself bonds to your follicles and they end up swelling.  When your hair follicles get larger, they are easier for the shaver to cut.

Another advantage to shaving with a wet electric shaver is that typically you will get a bit closer of a shave as opposed to using it dry.  So if you are looking for the closest shave you can get without relying on a shaver a wet shaver might be ideal for you.

Reviewing Battery Life in Electric Shavers

Electric Razor Charging Icon
This is probably the most overlooked portion when reviewing electric shavers.  However, if left in a pinch you could be in a hairy situation (see what I did there).

Lucky for you though, most electric shavers nowadays have an extraordinarily quick charge time.

I’m talking less than 5 minutes charging and you have enough juice to last you for the morning shave.  Yeah, they are that quick!

5 Minutes to Your Morning Shave

To note, that in most cases with electric shavers, you cannot plug them in and shave at the same time.

The reason for this is that since as we discovered a high amount of wet & dry electric shavers on the market, manufacturers put in a safety switch to prevent people from electrocuting themselves while trying to shave with their device plugged in while showering (no comment).

I know that you definitely wouldn’t try something like that, but if you’re wondering why your soon to be electric shaver seems broken when its plugged in, this is why.

You can expect from most shavers in the marketplace to yield an average battery shave time of about 45-50 minutes.

Another key feature to also look out for that is closely related to battery life is if they have a travel lock.  This travel lock is exactly how it sounds.

If you are off on a business trip, you can simply put your electric shaver into a lock mode so it doesn’t turn on while in your suitcase draining the battery away.

Keep Your Electric Shaver Clean to Prevent Acne!

Lets just say that owners of modern day electric shavers have it made.  Even if it is not a pure wet & dry shaver, more often than not, most electric shavers allow you to pop off the foil or rotary head and rinse it under water.

The easy convenience of being able to rinse the head of your shaver under water makes cleanup a breeze.

Of course most shavers still do of course come with the mini brushes that you can use for the hard to reach areas.

When looking at high end electric shavers you will come across several that have a docking and cleaning station (sometimes referred to as ‘Clean & Renew’).

What’s great about these cleaning system is their multi functional purposes.  The dock itself will clean the head of the electric shaver with alcohol, charge the shaver, lubricate the blades, and ultimately dry your shaver.

All of this is done when you simply rest the shaver in the cradle and click a button or two.

With the cleaning station however, there are some additional costs associated with it.  Every cleaning station requires a cartridge to be inserted (this contains the alcohol and lubricant).

Now this isn’t required to charge your shaver, so you don’t have to feel pressured to have a cartridge on hand in order to keep going (this isn’t like when the colored ink in your printer runs out and you only want to print in black and white but can’t because one part is empty).

Cleaning your electric shaver on a regular basis will help reduce the occurrence of acne as it will remove all of the natural oils found on your skin off the head.

With the cleaning cartridge, you can pick them up for pretty cheap and expect to spend around $60 a year on this total.  Each cartridge gets about 30 or so cleanings out of them.

Further Preventing the Spread of Acne and Irritation

When using an electric shaver, you want to make sure that you know how to use it correctly.  As outlined above in the foil head vs rotary head section.

Remember, foil head is used up and down or side to size.  While a rotary head is used in a clockwise circular motion.

One of the leading causes of irritation while using an electric shaver is when you go over an area multiple times.
Skin Irritation While Using an Electric Razor

This is why some people may opt to purchase a higher end shaver as it may reduce the number of times they need to go over their face in order to get a clean shave.

To help further prevent irritation, several folks opt for the shaver that has a wet shave option.  This way they can use their goto shaving cream in order to make the shave a bit more comfortable.

Wet Shave Electric Razor Testimonial

Regarding the occurrence of acne while using an electric shaver, as mentioned in the section above you want to make sure you can clean the head easily.

Also pre washing your face before you shave will help reduce the spread of acne.

Blades?  I thought I got away from using replacement blades?!

One of the major perceived benefits for electric shavers was that you don’t have to purchase blades.

Correct!  You don’t have to purchase them on a regular basis like your normal safety shaver, however, about once every year and a half or so, you should consider getting new blades if you are experiencing any pulling or gradual irritation thats occurred during the use of using your shaver.

Typical cost for replacement blades are still significantly cheaper than buying replacement cartridges for a safety shaver.  They will set you back around $30 for a foil head and about $35 for a rotary head.

Is the Cost of an Electric Razor Worth It?

Is an Electric Shaver Worth the Investment?

The biggest benefit to the electric shaver is convenience.  Especially if you are shaving on a daily basis.

Some guys who just need to get out the door quickly in the morning and can’t concentrate on sharpening blades, lathering on shaving cream, etc.  This is why there is a market for electric shavers.

Whether you are shaving in your car on your way to work, or just simply don’t want to worry about cleanup, electric shavers make sense.

Electric Shaver: A Wrap Up

So there you have it, an in-depth view at electric shavers and the key items to look out for.  So whether you are look for a highly rated shaver from Braun, or one of the top selling Norelco shavers, you know know what to look for when comparing them.

So what one are you going to pick?

      Main problem I have is the rotary heads break up into sharp metal bits. My first razor,Phillips, lasted 12 years. I bought fresh rotary blades all three broke up after just 18 months. I was forced to buy another but 2 years the heads went into little holes and the motor died. I now am in that position. Do I buy expensive or spend more for closer shave and lasting reliability and nothing else? To lash out on really expensive ones is tempting but something inside me says no. There must be something in the middle range for say 150 pounds that will last at least five years with no problems.

    Very nice post, way more helpful and informative than most of the other articles I’ve come across while trying to research electric shavers.

    Best article ever dude.

    Good article. After using electric shavers for 50 years, though, my other recommendation would be to consider electric over battery rechargeable. I have a dozen shavers, but am phasing out the battery models as they become more inconvenient as they get older…waiting to charge, discharging while shaving, throwing the shaver out when the battery fails. I buy/sell shavers on eBay (new and used) and I usually tell people if they have to shave on the go, or don’t have an outlet in their bathroom, the battery shavers are fine, but for consistent, continuous power, electric is better. I realize, some people can’t deal with cords, just like some people can’t deal with wired headphones, so for those people the battery shavers are fine. I find the rotary shavers take a bit longer and don’t shave as close as foils, but they are a bit easier to maintain. I have been able to keep foils/cutters for years by proper lubrication too…a drop or two of oil on the foil works well. Thanks for the good article. Gives newcomers a good overview of their options.

    If you are an aspiring writer, I encourage you to first become an aspiring proof reader of your own work; this article is full of grammatical errors. There are so many, that I couldn’t even really finish and still believe you are an expert on anything.

  5. Ajay Nabh says:

    I am new to this discussion and wanted to learn more. I find your write up to be very informative and easy read. Thanks and all the best with your future writings

  6. Bob Foss says:

    I agree. My wife is a former elementary teacher, and she is dismayed to find all kinds of errors in print, television, and online. Many people, apparently, didn’t pay attention in third-grade, she says. I try to overlook these and I buy/sell shavers on eBay, so I see a lot of horrible grammar. What’s worse, highly-paid “news” people on TV use bad grammar as well.

  7. no thanks says:

  8. David says:

    I had no problems reading or understanding the article and found it to be very informative. If you have a gripe about the ‘grammar’ used in a technical article … I would suggest that you have a bit of a problem and maybe need a bit of ‘couch time’

  9. I am inspired by your work and got some great ideas. Thanks and keep sharing 🙂
