Good product
This water flosser reminds me of the WaterPic of old (we had one when I was a kid, 35 years ago). It works fine for what it is.  I wouldn't purchase again, I would probably rather have a sonic water flosser, smaller.  Be aware that you will just about rip your dang gums off if you put the pressure all the way up. And keep your darn lips sealed tight or you will have water all over the bathroom walls. Wooo boy - it takes some getting use to, I do think it blasts water between the teeth pretty well.
