This is my second one of the same model. The last one still worked after 8 years but I wanted a new fresh one. My gums are much healthier since using my Waterpik
I'm totally loving my new waterpik. It still amazes me the food particles hidden between the teeth. I upgraded from my last waterpik. This is really another great Purchase.
Bought this for the purpose of being able to continue dental hygiene while on the road . Works good with the regular tip but not strong enough for the pocket tip. The water runs out fast even on the low setting maybe 30 seconds
