Title: waterpik ultra
Review: A nice product for blasting out the gunk from your gumline and between teeth. Makes a chugging noise but is minimally annoying and to be expected for a device like this. Be sure to follow instructions about shutting off the stream before you take the tip out of your mouth otherwise you will have water all over the place, or zap yourself with the waterstream which can be pretty strong. The side mounted on/off switch could be improved to make it easier to turn off the stream because right now it is side-mounted and so you might end up pushing it over instead of turning it off. If the switch was top-mounted it would be easier to press.
