Review (1/5): Useless
As inexpensive as this item was, it was still a waste of money.
1. The cap doesn't stay on when not in use, which means it will fall off in your bag.
2. The brush doesn't stay up/protracted when you're trying to use it, unless you keep your finger on the sliding mechanism.
3. I've had it for less than half an hour, trying to get it to work properly and the metal is already flaking off.
It's unusable, and with the metal flaking off I'm not sure that it's even safe. Tossed it in the trash.
