As so many of us have problems with our teeth after radiation I got a waterpik for Christmas, model wp-450. I've got to say I'm very disappointed. It seems to have very little pressure and I expected something more along the lines of what a dentist uses. It pulses and shoots water but not with any degree of force. My question is, Did I get a bad one, perhaps the battery isn't taking a full charge or is this what they are like. I don't know anyone who uses one to ask for comparison.
