Review (4/5): Love it!
I love this whole kit! It definitely feels like I've been to the dentist every time I use it - and the price was great!
The reason for the missing fifth star is because after the batteries that came with it went out after 3 weeks, I got new ones for it and there were no markings on which way the batteries should be put in. I tried them EVERY way they could possibly go and it still doesn't work. I'm very disappointed with that. So it looks like I'll have to get a new one. Debating on getting the rechargeable - that would just make things easier.
The kit is great though - totally worth it!
