I bought this for my husband and me. I had no idea what to expect as it has not been recommended by my dentist. And I am AMAZED! I have since bought one for each of my adult kids. My gums feel better and I had some recession that I believe is reversing. This is definitely a good buy.
It works as it said it should. All the extra heads were a bonus. Only problem I have is that when used and if you forget to dump out water it will drain out and make a mess on counter.
I am glad I started out with the lowest pressure and gradually increased it because this thing will peel the bark off of a tree. Works so well with my all on four dental implants and I highly recommend it for anyone that has them or bridges. My gums have never felt better. Thanks!
