I have owned my waterpik for a few weeks, and am enjoying getting acquainted with it. I look at all the different attachments, and haven't tried them out, but just stay with the one that I started with. I got the device because I have several bridges in my mouth, and I needed to get under them to force out the food particles. This works perfectly! I would suggest that more information be provided about the different attachments.
I bought this machine a month ago and I'm really impressed with how well it works. My gums feel much tougher and my teeth are much cleaner than with brushing alone.
Replaced my 20 year old WP that finally gave up. Love the new attachments and accessories. More benefits for my 70 year old teeth. I expect the same long life as my first WP. Great buy .
