The Remington MB4040 is one of the best beard trimmers for men. It can trim mustaches, beards, or stubble very close to style with a total trimming range of 1.5-18mm.

These trimming range specs are amazing, since this category is full of different length trimmers that do not have the range. For beard trimmers this is crucial, so that they can get the close-up trim on the chin that the MB4040 does.

The sizing for all of them is similar but where the MB4040 really stands head and shoulders above the rest is that it has 9 length settings to not just get the even beards but the slightly longer beard styles and stubble to give them that professional feeling each time you come to find someplace new to trim.


The unit works with a standard household 120-volt outlet. You can even charge it while you are using it. To use the unit you simply slide the power button on and off until you see the little light flash to let you know that it is fully charged, and then you turn it on and use it. The unit can run for up to 120 minutes on a full charge, and you can even recharge and go again too.

Wet & Dry

You can use the unit whether you are wet or dry. This unit got designed for wet use, so you can surely expect it to work great when you are using it underwater in the bathtub or with the unit.


Compared to other trimmers out there this one can do all sorts of things. It can trim your eyebrows, men's scruff and your beard as well. The gadget also comes with an attachment that you can use to clip on to it to help trim your ear hair too.

Laser & Design

You can either use the laser designs to line it up to the area you want to trim, or you can just edge it with one stroke.

Whats In The Box?

In the box is the trimmer, a charging station, quick charger, and even a smaller compact razor-like trimmer attachment. The pretty good looking compact attachment even has a OLED display and can show you in a nice see-through design all the extra information that is about to come to your screen.
