I've had this waterpik for two years now and I love it. Pressure is great (I leave it on 5 -- I can't imagine turning it any higher, it's quite strong). I am an adult with braces, this has been invaluable, I can't imagine life in braces without it and I'm looking forward to using it once I'm out of braces as well. Flossing is great, but this is the best.
