Review (5/5): It works! No gimmicks at all just perfect.
I read the reviews and now I can give a true and honest review. This works and doesn’t hurt at all. I used the lie volume and was able to tolerate the vibration. It scraped the plaque gently from my teeth. I tried the faster version but decided to stick with low version until I have used it for a while. This is worth the money so buy it while it’s available.
