While I still like my sonicare toothbrush best and think it does a suburb job, this Crest brush is one of the better low-cost electric toothbrushes. It is good if you don't want to spend the money or if you are concerned you might break an electric one and don't want to waste tons of money. I don't like the circular rotating brush as some of the others, but this still seems to clean well. Performance/Cleaning Again, not as good as the Sonicare system, but it does seem to be better than a lot of the other electric toothbrushes in this same category. It's movement does a good job not hurting your teeth/gums and it's vibrating bristles do a good job getting your teeth cleaner than a regular toothbrush normally does. Durability This is better than some of the other varieties in the same category. I had better luck with it lasting longer than its competitors brands, especially with kids who I am sure are rougher with toothbrushes than I am.
