Thumbs up
Noticed the difference with one time use. I've used a sonic toothbrush for several years. The darn thing never broke down. Decided to look for a new one and Planned to spend below $100.  I found this highly rated $36 sonic cool and thought I'd give it a try. Wow!  Noticed from the first use how super clean my teeth felt. I was very happy with my purchase, so much so that I bought 5 more for family members for Christmas.
