Review (1/5): Its a toy.  Not a real thing that can cut hair
This product looks too flimsy and it looks more like a play toy. I am surprised they sell this seriously as real product that can cut hair. Hair gets stuck the minute you tried to cut the hair. Hair guard came loose almost immediately. I don't see how this product can work on full head of hair.
At best it trim a beard. But I don't grow beard. So, this one is going back.
