The Norelco 4100 Electric Razor: Your Path to a Clean Shave

Electric Razor

Electric shavers, such as the Norelco 4100, have a unique place in the annals of U.S. innovation.


Electric razors help take the pain out of shaving. They eliminate the risk of nicks and cuts and the expense of replacement blades and shaving cream.

Jacob Schick was a retired U.S. Army soldier when he received the first patent for an electric razor back in 1928.

His first electric shaver went on sale in 1931, and he parlayed its success into one of the most recognizable brand names in personal care. Schick razors (electric and otherwise) are a mainstay in the shaving section of your supermarket.


Electric razors help take the pain out of shaving. They eliminate the risk of nicks and cuts and the expense of replacement blades and shaving cream.

They also bring a level of convenience, allowing you to shave anywhere in your house rather than standing in front of a half-filled sink of cold water scraping your face with a disposable blade.


Not all electric razors are created equal, though. Some come with heftier price tags than others. You can also buy packages that include different grooming accessories.

The truth is: The Norelco 4100 sits in a crowded market of electric shavers. Is the Norelco 4100 your path to a smooth shave? Maybe. But first, you need to know more about electric shavers in general.


Evaluating Electric

Electric shavers offer two different designs.

The first is the foil shaver, built with opposing oscillating blades that alternate directions at a high rate of speed. Some foil shavers come with three and four blades and are best for straight-ahead shaving over larger areas (such as shaving your head.)


The other type is the rotary shaver, with blades aligned around a rotating disk. The blades spin in a tight circle as you move the razor over your face. Many say rotary shavers provide closer shaves.

Beyond design, there are some practical considerations in deciding which shaver is for you. Perhaps the most important is battery life. Look for shavers that offer upwards of an hour of run time.

Consider also cycles per minute. The more times the blades rotate or oscillate, the sooner you’ll be done with your shave.


Finally, consider what else comes in the package. Some razors differentiate themselves by adding certain accessories, such as trimmers for nose and ear hair.

Once you've factored in design, speed, lifespan, price, and accessories, you've got all the information you need to decide.


Introducing the Norelco 4100

Philips Norelco Shaver 4100 (Model AT810/41)
  • Shaving time : Up to 17 days
  • Highly durable blades
  • DualPrecision heads are designed with slots and holes to quickly and comfortably shave both long and short hair
  • A great gift, the shaver's Aquatec Technology allows you to shave wet with gel or foam for extra skin protection or dry for convenience
  • For best results, replace shaving head every 12 months with SH50/52 replacement head

Today’s electric shavers offer a wide range of features and price points. You can find no-nonsense, just-give-me-a-shave models up to highly engineered razors with sensors and unique materials for improved performance.


The Norelco line of shavers, including the Norelco 4100, reflect this comprehensive set of options.

For instance, for several hundred dollars, you can get yourself a shaver from the Norelco Prestige line with Nano-technology blades, metallic pigments, and sensors that judge beard length. But you can also find basic rotary shavers.


The Norelco 4100 is part of the brand’s 4000 series of wet and dry shavers. It’s more toward the lower end of the line. Let’s look at what it offers for shaving comfort.


Customers and Comments


How We Reviewed

Let's be honest: No one really likes to shave. It's a thing we do as a matter of proper grooming and better looks. There are plenty of resources out there to help us make the best of a bad situation.

For this review, we started by digging into the Norelco website. That, we felt, was the best site to give us an understanding of the types of electric shavers in their line and how the Norelco 4100 fit in.


We also looked at lifestyle writers who put together best-of lists for electric shavers, in publications such as Business Insider, Gear Patrol, and Men's Health.

Then, we looked closely at the features and benefits and spec page for the Norelco 4100 to tell you what the razor does for you.

Finally, to round out our resources, we looked at reviews from people who have bought and used the razor, both on Amazon and BestBuy.

Alternatives to the Norelco 4100

Our research on electric razors wasn't confined to the Norelco 4100. As we alluded to earlier, electric shaves represent a big market.

We examined three competing razors in greater depth for comparison purposes. Whichever choice you make, stay focused on the basics of battery life and shave closeness.

Panasonic Arc5 Electric Razor

Panasonic Arc5 Electric Razor, Men's 5-blade Cordless with shave sensor technology & Wet/Dry Convenience, ES-LV65-S
  • Sharp Men's Shaver Blades: Panasonic Arc5 men's electric shaver with five ultra sharp precision honed 30° Nanotech blades and ultra thin Arc foil follow facial contours for a quick, close and comfortable shave
  • Wet/Dry Electric Shaver and Trimmer 2 in 1: Built in pop up trimmer details mustaches, beards and sideburns; Wet/dry waterproof shaver allows for convenient shaving in or out of the shower
  • Multi Flex Pivoting Head: Panasonic flexible pivoting electric shaver head glides effortlessly to trace the individual contours of face, chin, neck and jaw; Built in shaving sensor monitors differences in beard density and automatically adjusts cutting power for exceptional comfort
  • High performance Motor with a Linear Drive: This Panasonic shaver is equipped with a linear motor which delivers 14,000 cuts per minute (70,000 crosscutting actions per minute) and maintains peak power up to the end of every battery charge
  • LCD Battery Indicator: The shaver's 10 stage LCD shows battery status at a glance; Rechargeable, portable and travel friendly

To provide a contrast, our first alternative to the Norelco 4100 is a foil razor. The Panasonic Arc5 Electric Razor is a wet or dry shaver for use in or out of the shower.


The unit offers 5 blades, angled at 30 degrees, which Panasonic believes will provide an optimal shave experience. The Arc5 is also designed to pivot as it moves across your face.

The price is a bit higher than the Norelco 4100, but not the highest we saw on the market. For the extra money, you’ll get the benefits of an embedded sensor that adjusts based on the length of your beard on a particular day.

Accessory packages are similar to the Norelco 4100 -- the shaver includes a pop-up trimmer for fixing mustaches, beards, and sideburns.


Positive reviewers comment on the quiet nature of the razor. They also appreciate the information-rich LED screen, which shows how much time the shaver has been in use and the battery life left. Several users wrote about the speed of the razor as being particularly impressive.

Reviewers with less positive comments experienced unexpected mechanical failures. However, even in those instances, the reviews note that the shaver performs well on their face.

Venyn Rechargeable Electric Shaver

Venyn 4 In 1 Richor Rotatory Electric Shaver - Works for Wet, Dry Beard - Body Hair Trimmer - Water Resistant -Cordless Face Cleaner
  • MULTI USE KIT: The product includes 100% stainless steel electric shaver head, trimming head, beard brush and a nose hair trimmer to provide you a protective shave with versatility at its best.
  • EFFICIENT BATTERY BACKUP: Power outages right before an important meeting? The MaxLithium power of the shaver provides 60 minute cordless runtime after 90 minutes of charging.
  • DRY/WET SHAVE: The Richor Rotatory Shaver by Venyn has a washable design that not only gives you the option of a comforting dry shave but also a refreshing wet shave with or without the gel or foam.
  • 3D FLOATING HEADS: The rotatory heads use the 3D float system, automatically adapting to the contours of your face, neck and jaw. This allows the heads to flex 360 degrees for a more productive operation, giving you a salon experience of the smoothest and safest shave.
  • QUIET HIGH SPEED MOTOR - The premium quality motor is not only efficient but quiet as well so you can enjoy every moment shaving

As an alternative to the Norelco 4100, the Venyn Rechargeable Electric Shaver offers quite a bit of value based on what else is in the box.


Besides the shaving unit, Venyn also provides a precision trimmer, nose hair trimmer, and a rotary brush. (The brush is for cleaning your face.) The price for all of this is less than what you'll pay for the Norelco 4100.

Venyn’s razor is also available for dry or wet (in the shower) use, with or without shaving cream or gel. It's fully washable to keep older hairs from creating further problems down the road.

Unlike other shavers, the Venyn unit is charged via a USB cord. The company promises an hour straight of run-time and a full charge in 90 minutes.


Positive reviews comment on the nose trimmer as a useful addition and the ease of cleaning. Reviewers also note that the shaver runs very quietly.

Negative reviewers had bad experiences with the longevity of the charge. Several complained about the razor having a cheap feel to it, while others didn’t like the shave it provided.

We looked at some of the biggest brand names in electric shavers for our Norelco 4100 review. But you don’t necessarily have to, as there are well-regarded products with less recognizable brand names.


For instance, we liked the EUNON Electric Shaver for Men. This shaver charges in an hour and promises 90-minutes of continuous use on battery. That's among the best battery specs of razors we reviewed. You can also use the razor while plugged in.

One of the features that struck us as unique was the ability to mute noise from the motor (so you don’t wake the kids in the early morning hours.) This rotary shaver offers a shave head that flexes in four directions.

We also like the smart LCD screen. The screen displays battery status in percentage terms, which is easier to act upon when needed.


This razor also falls into the wet and dry category. It's available for use both in and out of the shower, with and without gel or shaving cream.

Positive reviewers felt the EUNON shaver offered great value for the money. They found it as durable and practical as shavers from some of the better-known brands.

Less enthusiastic reviewers had poor experiences with the unit. A few reviews mention that they didn’t feel the shave was close enough or, conversely, gave them razor burns.


Smooth Skin

Shaving is a chore that we all, men and women alike, contend with daily. And the competition for you to buy one, for the sake of convenience, is fierce.

Given the affordability of razors today, we'd suggest you dive in and give one a try. But don’t worry about finding the perfect shaver right off the bat.


Start at the lower end. The Norelco 4100 will let you get a sense of the world of electric shaving without requiring a significant investment.

For us, the key is value. We liked the razors we reviewed that offered extra attachments for nose hair and other grooming tasks.

But at the end of the day, it’s going to all be about the closeness of the shave. Given one a try and see how it works.
