I bought this a couple of weeks ago and am so glad I did. I have receding gums and the toothbrush would irritate them. I find now that my teeth feel cleaner and look cleaner and my mouth is fresher. Only downfall is that the eject button for the pick head seems to occasionally trigger when I'm busy cleaning my teeth ... maybe my hand is accidentally touching it while holding the handle and moving it around my mouth.
I bought this because my son's orthodontist recommended getting a water flosser. It was a great suggestion because the machine has really helped my son keep his braces clean. He likes using it and it's effective. My only complaint would be that it is a bit loud, especially when the pause button is being pushed.
Power switch broke after 5 months of use. No longer usable.
No, I would not recommend this to a friend.

My husband and I use this nightly when we brush our teeth before bed, or after eating foods high in protein that get caught in our teeth. It is very easy to use, and cleans our teeth excellent!
