Title: Good; but could be better
Review: I have been a Waterpik user for a few years. My last model had great water pressure and large water reservoir; but it's performance started to decline.The Ultra comes with a smaller reservoir and the highest pressure setting does not match my previous model. Waterpik might have perform some studies and found that the pressure is adequate; but the reservoir capacity must increase in the next model.All in all, it gets the job done and is much quieter than the previous model.
Is the review positive or negative?
