First off, ordering it from the UK, I was hit with a hefty customs charge - making it a very expensive brush.
However, it is the brush itself that I have a problem with. It is rubbish.
It barely vibrates, in fact, I really don't see the point of this at all, as you have to use it like a normal brush. I wanted it as a travel alternative to my Braun, but in fact, I should have bought a disposable brush - it does a better job for less than $5/£4
Bottom Line: No, I would not recommend this to a friend
