We have only been using the toothbrush for a few days and on the whole it’s a good product. My wife and I share the toothbrush and she much prefers the oral B unit it replaced. At the moment I do also but will keep on going to see how it works out. My thoughts are that maybe the toothbrush part itself could be a more rubberised material as the hard plastic vibrates on my teach when moving around the mouth. The simple lower setting is therefore the best to avoid this as the 2 higher settings I find a bit too much. One other point is that the brush starts automatically on the higher setting which I think is not the best as you have to go down to the lower setting quickly to avoid disconnecting… starting on the lower setting would make more sense to me. Lastly a pack of 3 toothbrush heads looks expensive.
