Review (2/5): Not worth it.
I would recommend anyone who seriously cares about their beard to buy something else. I had teeth on the comb break off in the first couple of weeks. It is very easy to burn yourself as well. It defiantly will straighten your beard but I bought another hot comb that was just better constructed and haven't burnt myself. The other problem I had was the plug to this was not made for American outlets, not a huge problem because it cam with an adapter. But, it made it bulky and a bit more of a hassle to pack on trips. Overall it will work and proved to me that these aren't a gimmick. But if you care about yourself at all, spend $5 and buy something nicer. It will last longer because by the time I replaced this 5 teeth broke off the comb.
