Review (3/5): Great concept, but not the best out there.
I’m torn about this toothbrush. I switched to ultra-soft toothbrushes a long time ago and it made an immense difference in the overall health of my mouth. I love the idea of this toothbrush, but the nano-size bristles are packed together sooo tightly that a lot of toothpaste remains stuck in the brush after you’re done, and no matter how intensely you rinse it, you can’t get it out. Also, it took a good week for the bristles to start to fan out a little bit, which is necessary to actually brush your teeth properly. Again, I applaud the concept, and maybe I should give it another chance, but after a week I just couldn’t get a good brushing out of it and my teeth never felt truly clean. So I use it for cleaning grout now (it’s awesome for that).
