SUPRENT Beard Trimmer for Men Waterproof, IPX7 Professional Mustache Trimmer, 39 Built-in Adjustable Precise Lengths, Cordless USB C Rechargeable & LED Display

The key to this thing is the dial-o-matic beard trimmer guard, which allows you to adjust from a 1, which is good enough for a nearly clean shave, to a 10, which is good for thick beards. It adjusts in half sizes. I really appreciate not having to keep a handful of beard trimmer attachments in a drawer or bag. This is one unit. USB charging, and the charge lasts a very long time. I've bought four of these. One dropped on the ground from 20 feet up and cracked the beard guard (but the damn thing still worked!). Bought myself another and bought one for each of my sons, who also love it. This is the way the Lord our God intended shaving.

My husband loved the trimmer, great, easy to clean. Functioning just as described. Thanks amazon for the service, made everything closer to the customer and always we appreciate the delivery service.

This trimmer exceeded all my expectations. It is very practical, lightweight, and easy to use. I love that it comes with several accessories, including an adjustable comb, USB-C cable, oil, and cleaning brush, which makes it very complete. The battery lasts a long time and the digital charge indicator is a very useful feature. Plus, it can be washed without any issues since it’s waterproof. It cuts precisely and smoothly, perfect for both beard trimming and hair touch-ups. Highly recommended, an excellent purchase!

I have been cutting my own hair and trimming my beard in the shower for over a decade, so I have used many water proof/resistant trimmers. This is one of the best I have used. It is easy to use, great design, sleek looking, long battery life. The only negative (and it can be a big one) is that mine broke in 3 months. There is a design complexity that the level change is done by some internal gears and a dial you turn. Within 3 months, the dial stopped moving the trimmer length and suddenly a "number 5" turned into a close buzz cut because the length wasn't adjusting. That is a big problem from a product quality perspective, but it was more than made up for by the vendor's great customer service. I told them of the problem and they responded quickly with a replacement unit.

The item is well designed and made of good material. The item was easy to use, with the simple button. The item charges are relatively fast. The battery life is a decent quality. The trimmer has adjustable attachments that help with fading the beard properly. The item is a good value for the money.

Got it in March 2025, worked well until it started to lock. There is a mechanism for locking. It wouldn’t open up (yes I’m using the manual). The seller is no where to be found. Don’t waste your money!!!

I'm very satisfied with this machine. It has a modern design, is lightweight, and is comfortable to use. I loved that it's waterproof and has a digital display as a battery indicator. My husband loved it because he doesn't have to go to the barber as often anymore. I think I'll buy another one for my dad.

I've been wearing a beard for nearly fifty years now. This beard trimmer is by far the best I have ever owned. It is wel built, solid and finely finished, The two adjustable combs are a great improvement over other trimmers that have multiple clip on combs. Highly recomemded.
