It works the same as any normal wide tooth comb. Not worth the $16
[[VIDEOID:56a0b156d42ea912478dbdc15191bb5c]] It vibrates, only a little. I have medium thick hair and it gets tangled easily. I wanted something to help with the knots. I don't think this product is that. I read other comments and quite a few said it didn't work but lots said it was great so I took a chance.<br /><br />First, it's 2020, if it's going to be battery operated, get a battery cover that snaps in and doesn't require a Philips head screwdriver. Although it does come with the screwdriver. But I don't understand why it's not USB. Minor gribe, but I imagine it's annoying if you were to lose the tiny screw.<br /><br />Next, but the main reason I'm returning this, the teeth rotate but that seems broken. That just leaves a loud vibration, which is not strong. It worked just as well off as it did on. The design of the comb teeth are nice to get through knots, but with all the hair care options out there I'd rather find something else that does the same thing without a battery, or works as I'd expect.
