I think the toothbrush is great, especially because it cleans the teeth from top to bottom, the way you're supposed to. Most other electric toothbrushes don't do that. My teeth feel very clean, and the soft bristles are very gentle on my gums. The only downside is that it's extremely uncomfortable when you accidentally touch your teeth with the back of the brush head while brushing. The strong back-and-forth movement of the brush head hurts. I wonder if this could be prevented, perhaps by adding a cover around the back of the brush head that doesn't move.
