Unbelievable, best thing since sliced bead (to coin an old term). Outstanding, I use it twice a day and my teeth haven't felt this good in years. ; - )
I bought this about a month ago. Like the convenience of the size as before I had a larger one which was not good for travel. I do not think it is as powerful as my first one. It is also hard to use on back teeth since you need to hold strAight. Liked having on those so it turned easier.
After a few dental visits and it was suggested that I purchase this product, I am so happy that i did..It leaves my mouth feeling great after each usage.....
