Recently I have been using the Remington Diamond MB320C Beard Trimmer and I have to admit I've been really impressed. Having tried numerous trimmers and shavers throughout the years I have finally found one that actually works as it should. It's head and shoulders above the rest in every aspect.
Most importantly the Remington trimmer actually trims your facial hair well and leaves it looking exactly as you had hoped. Unlike every other trimmer I have ever used there are no uneven hairs here, or big gaps where the trimmer has somehow trimmed the hair to a much shorter length in one patch.
The main reason for such a neat finish is mainly down to the guard; it's shaped well to fit the contours of your face and the blade is covered on each side so there are no accidents. There are nine different length settings to chose from and one charge gives about 2-3 hours trimming time. There is also a handy warning light that lets you know when the charge is running low.
If you are on the hunt for a new beard trimmer and are fed up of products promising lots but not delivering, then you should give the Remington Diamond a try. You will be impressed.
