Purchased on my dentist's instruction and I'm glad I followed it. This easy to use device really gets out what was left behind after a through brushing with a good electric toothbrush. Easier for me than flossing.
Bought new water pick to replace top holder and pick tips. If I would order these parts and paid freight it would of been about half what a new one cost. This way I have a new unit and kept old one for parts if needed. Old unit was probably 3 years old.
We bought a Waterpik about a month ago and it works great. You have to get used to the different water pressure and letting the water flow from your mouth but both my wife and I are happy! We think it works better than floss! A Wonderful Product!
