Review (5/5): Great beard trimmer
If you're like me, you start out reading the 1 star reviews to find out what's wrong with a product. You will see a lot of alarmist reviews claiming the trimmer shifts length settings without the person knowing. This does happen, but if and only if you have not set the razor attachment on correctly. The razor comes with a beard trimmer and a mustache trimmer, which involves switching attachments. Not setting the attachment on correctly will cause problems. However, if you set it up correctly (not difficult), then no problem occurs.
I like this razor because it has a long lasting battery, which makes the whole process much easier. It cleans easily, and captures a good amount of hair to prevent a giant sink mess. It cuts well, and accurately, although it does take me a while because you have to keep going over the beard to make sure all the hairs are cut to the same length. The mustache trimmer is a great addition as well, because it allows for some precision.
So assuming you can figure out how to work this product correctly, it should do exactly what you need it to!
