Review (3/5): Brushes are Nice but hard to keep clean
The brushes work well-- However, they're the first tooth brush i've ever had where I've had the problem of small bits of food getting stuck in between the bristles. Rinsing alone doesn't get them out and I have to use a little pick to fish them out. Otherwise I really like the experience of using them, I just don't know if they will really be more sanitary than a regular tooth brush if food particles can rot inside of it.
Update: I've lowered it to 3 stars as they are really quite unhygienic with how difficult it is to remove small food particles from them. Today, I finally found the best way: with a water flosser. Ugh, so much stuff came out despite the fact I had been trying very hard to keep it clean and remove debris with my dental pick. You shouldn't need a $30+ gadget to be able to keep your tooth brush from getting so filthy so quick.
