Review (5/5): The best 8 bucks you could spend.
If you've made it as far as reading this review, just pull the trigger already! It's only a couple bucks!
You can get a nice dentist-fresh clean from the comfort of home for an absurdly good value.
The tools work great. I like to do a weekly deep cleaning with these to complement my daily brushing routine and prevent any kind of crud from building up.
