The cleaning result we are very happy, I would not go back to a non-sound toothbrush back. However, I had no other sonic toothbrush and therefore can not compare that. But we've also had several times the problem, have the other described here: The toothbrushes have ceased to brush (just the engine still works, but the brush is no longer moving). At first we thought we had left it too often fall and bought them new. Then I read here that this is a quirk. The next control with the symptom we got without hesitation exchanged for a new one. But if the warranty has expired, and the handle is broken again, I would try a different sonic toothbrush.
