4MAS Trimmer Review

How to Choose the Right Trimmer for Your Beard and Hair


In their most basic form, trimmers are used to trim hair from the neck and shape the sideburns and the nape of the neck. Moreover, they can be used to taper, bald a head, or establish the first guideline in a bald fade, shape-up, and create beard and mustache edges. Trimmers are principally guarded mechanized cutthroats that you use to help make guides before using a real razor to shape up. 

So, we can say that trimmers play an important role in our lives. As a necessity, we should get a good one that will last long. If you stumbled across this piece, you are in the market and looking for a trimmer that suits your needs. If you want to know about 4MAS Trimmer specifically, you’ve come to the right place.

What Can a Trimmer be Used For?

Because of the size of the blade and teeth, trimmers are made to cut (or trim) shorter, thinner, or coarser hairs, such as facial and body hair. Trimmers are designed to focus on the delicate details of the beard, face, and body by cutting closer to the skin.

Trimmers used to cut hair have two or more sliding blades. Your hair is cut as it is run through the blades. Zero-gapped blades can do more good for you as their cutting is more precise than a regular trimmer. Additionally, they can be used for finer hairstyles, such as fading, and can be used to cut straight lines for the lineup technique.

In addition to trimming the beard, trimmers can also be used for detailing and trimming facial hair, such as sideburns. Most trimmers are nimble and have narrow cutting widths. Trimmers cut hair precisely because of its narrow width and small size. 

Due to their versatility, trimmers are favored for styling facial hair and hair on the head. Trimmers, however, are not just for trimming facial hair. When necessary, body hair can also be trimmed. The guards and attachments that come with trimmers are different in size but function similarly to those with your clipper. 

Features of 4MAS Trimmer

Zero Gap 

An outline of a haircut is essential to make your hair look amazing. There are many hairstyles and many basic hairstyle techniques that need incredible precision. A lineup is something we notice first when we see a haircut. This lineup technique is made of straight solid lines. Straight lines and right angles define the hairline in this style. 

Another haircut technique employs a similar principle when it comes to defining lines: Fading technique. This technique, in its simplest form, captures a change in the length and color of the hair on the sides and back. This indicates that the hair has a variety of lengths mixed in rather than being buzzed to the same length throughout.

How high on the head the shortest portion of hair reaches before beginning to transition into a longer length determines the level of the fade, which can be taper, low, mid, or high.

These haircuts need a device that can cut with precision. How can this be achieved? If you’ve never heard before, we present a term that is called “zero gapped.” A trimmer with a zero gap means that the cutting blade is brought closer to the guiding blade.

If you take a closer look, you will realize that there is one blade that is stationary, and there is another movable one. You can achieve straight, solid lines when these two blades are closer. Many try to create this at home when a trimmer doesn’t have this feature. But why bother with it when you can buy a trimmer with a zero gap?

4MAS Trimmer comes with this quality. It’s zero-gapped, as it promises to be. Now, you can try your hand at your favorite hairstyles with no problem. As we have mentioned before, the foundation of numerous hairstyles depends on straight lines that can be achieved through precise cutting. Being zero-gapped provides precise cutting, and 4MAS doesn’t disappoint in this regard. 


We usually question whether or not a product is convenient whenever we’re looking for something to buy, especially if they are more of a smaller kind. And with trimmers, we want them to be ready at hand. Shall we take a look at 4MAS Trimmer’s ability to be convenient? 

The first thing we would like to mention is that the 4MAS trimmer is cordless. You can charge it with a USB cable that comes in the box and use it after it’s done charging. This quality comes in handy since when trimming your facial hair or the hair on top of your head, you must have room to move the machine to have a comfortable trimming experience. Being cordless is also essential because you should have more flexibility to prevent accidents. It is especially important with this one trimmer due to its specialty of being zero-gapped. 

The product comes with three different guided combs that can be attached to the head. So you can change them for your various needs. They differ in terms of gaps between the teeth of a comb. Take your pick! In addition, it comes with a cleaning brush that is easy to use. It can clean the guided combs and the blades.

You won’t need another cleaning technique. The only downside would be that the battery life is short. So if you are in the business or trim more than a few heads, you will run out of battery. However, it does not take too long to charge. So you shouldn’t have too much trouble with this model.

Easy to Use 

Being easy to use is perhaps one of the most wanted qualities you can have in a product. It is needed when it comes to products that can potentially harm you or change your look for some time. Some of us go to a barber to get a haircut or clean shave. If you want to achieve a clean cut in the comfort of your home, you must own a trimmer that you will have no trouble using.

The 4MAS trimmer is easy to use despite being so sharp. While being sharp is a very neat feature, it may lead to some small accidents. However, it is less threatening when the trimmer is efficient and can be used easily. It is cordless. This means you can move it however you like, and you will be less prone to accidents. Its flexibility doesn’t just come from being cordless. This trimmer is also easy to maneuver, giving you a comfortable trimming experience. 

The 4MAS trimmer is also lightweight. So when you are trimming your hair, you will move the device easily enough, and your arms won’t suffer from its weight in the long hours of shaving and cutting. 


A product’s quality can hint at how long it will last and how durable it is. We all believe that investing in expensive goods that will last longer is preferable to purchasing fairly inexpensive goods that will need to be replaced more frequently. A trimmer’s quality can be revealed by assessing the blades and material of the entire product.

Another reliable metric is the lifespan of the batteries and how long it takes before a charge. Now that we know what factors to consider when evaluating quality let’s get started.

4MAS Trimmer has sharp blades that will easily cut through coarse facial hair. It will also have no trouble styling your hair as its blades are high quality. Its design makes it so that you have the best trimming experience and benefit from the blades in their full quality.

 The model of the 4MAS trimmer is zero-gapped. As we have explained before, being zero-gapped means bringing the guiding blade and cutting blade closer. This indicates that the cut of the hair will be precise, and this also means that the consumers will experience no skin irritation. As you may know, the skin gets irritated when you use blades on it repeatedly. You won’t have these concerns with the 4MAS trimmer since you will only need to go over the surface of your skin once. 

The overall materials are high quality, and the trimmer will be with you for an extended period. We can say that the skeleton design is durable. However, we can say it is a bit of a problem when it comes to battery life. It doesn’t take too long before you need to charge them again, depending on how long it takes for you to trim your hair. They charge quickly, in 45 minutes. In some cases, their charge isn’t enough to shave everywhere fully. Especially if you intend to trim more than a few people’s hairs, it won’t be enough by itself. 

Final Verdict

4MAS Trimmer is a high-quality product that will last you for more than a regular trimmer would. It is zero-gapped so that you can get those clean and straight lines you have always wanted in the comfort of your own home. If it’s zero-gapped, then how come I can be comfortable?

Of course, you will need to be careful when using any blade, but you should be extra careful with zero-gapped trimmers. It is easy to maneuver, and it is flexible. It is all thanks to being very lightweight and cordless. So we can say that these trimmers are less accident-prone, although please do be careful.

The charge probably won’t be enough for you if your business takes too long, however, it charges rather quickly, so you won’t have to wait for ages for it to be charged to go about your business. It comes with a cleaning brush. It is easy to clean as it is easy to use. You won’t need another way to clean.

It comes with three different guiding combs so you can have your pick according to your needs. It is cordless, giving you more room to move, and you can take it with you even if you don’t have somewhere to charge it. It will be useful for a while. In conclusion, we recommend this product since it has good features and doesn’t cost an arm and a leg.

Review: By far the best clippers I’ve ever used. I lost the charger, they helped. I had troubles about 6 months after having the clippers, they helped immediately!!!! I’m not switching back to no other barber products!

JMacDaGreat – ⭐⭐⭐⭐

Review: Love these trimmers, good blade, and gives crisp line ups…the only problem I have with them is that one side of my hair guard has broken off even after being very careful taking it off to clean. Also I wish the battery was longer, after about 2-2.5 line ups they need to be recharged
