I got this a few months ago from Amazon for only $39! I think it was so cheap because it didn`t come with the fancy packaging, but had everything the full version would have. It works great BUT the reason it has that funny rubber thing on it is because mold forms easily on the inside where the head connects to the base! EWW! So I cut the finger off a rubber glove and tried to seal the part where it connects to water can`t get in there and create mold. Mold is the last thing I want near my mouth when I am trying to clean it! I think this solution is helping even though it looks weird! I wouldn`t buy this toothbrush again because of that mold issue though. Just a warning if you are looking for a new toothbrush!
