Fat Teeth
I've never had a beard straightener before but it sounded like a good idea. What I pictured was something about the size of a fat comb. Instead, this device is the size of a very large hair brush. Moreover, the individual teeth of the comb are the diameter of a spaghetti. In other words, this straightener seems more appropriate for someone with a large head of hair rather an old man with a slightly unruly beard.  Nonetheless, despite its inconvenience, I must say when I do bother to use it, my beard does look straighter which is to say better.
