Review (3/5): definitely not professional tool
My son tried this out on his beard to shape it up. It didn't work well on the beard part, but was okay in taking off the fine hairs on his cheeks. The whole set up is very flimsy, feels cheap with just a so so outcome after use. This might be good for anyone just starting to shave that might want to graduate to a straight edge down the road. Just don't expect professional results if you have an established beard you want to maintain. My son's beard is not particularly dense but enough so that this is a no go for him. Maintaining a light beard or the 5 oclock shadow look might be possible.
