I brought it years and it is used everyday for my wife and me. We deeply recommend to everybody, especially if you have any kind of crown teeth, implants or bridges.
I am so impressed with my purchase and so happy with the space saving feature as well as the awesome storage features for the intercahngeable heads. I highly recommend this to anyone. I also the love how light weight it feels and how gentle it is on the gums and teeth. My whole mouth feels so Clean!!!
Bought WP-900 a month ago. Very satisfied with both the Waterpik and the Electric Toothbrush. Nice small size machine. Easy to use, with lot of optional attachments. Nice storage for attachments, also.
