Review (3/5): Newe Model Toothbrush is Better, but this is still good option
I've been hooked on Sonicare tooth rush once I tried it. Love that it has a self timer so you know when to move from front to back, side to side. Learned to dry it off after every use when after a few months I noticed some discoloration under detachable brush head. Not sure if it was mold but was difficult to clean the inside. I do like this toothbrush and recently got the newer model and they solved the cleaning issue by making the way the brushhead attaches not have s bunch of open space when bacteria and mold can grow. I give the newer version 4 stars, very haiku with it. My teeth feel clean and smooth.
