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!
I only wish it had an automatic filling feature such as a ice maker so as you would not have to keep removing the water storage bowl for filling. And the shutoff for the water line should be built in to the on off switch so as if you should leave the brush holder laying on the counter the water would not be leaking all over the counter!
