Have been using for about a month now...it took some getting used to, the mirror has been sprayed a few times when I forgot to pause it. Overall, I like it. Only complaint is that its noisey, can't use when family members are asleep.
My husband and I use our Waterpik every day. We're on our third one. My only suggestion would be to have the lowest settings to be a little softer. We have two teenage grandkids with braces who use the smaller appliance.
The simplest statement is the best in my view. This product does exactly what it is designed to do. Great features with the brushes, cleans the teeth and exercises the gum lines, and removes food from in between teeth.
