Best thing ever! I try to floss daily, but let’s be honest, sometimes it’s just too tempting to skip it. Not after I got this water flosser! This thing is amazing and very efficient. Not sure why people are complaining about it being too powerful. You need a jet to get the job done, otherwise it’s rinsing, not flossing. It’s the same strength as what they have at the dentist’s office. I bought one for myself and then my husband wanted to get one too. He has very tight gaps between his teeth and he loves it too. No more stuck and ripped floss! I had some gum bleeding here and there - all gone after two uses. I got another one for our teenage son with braces and (!!!) he loved it too. The water tank is enough for roughly 1/4 of the mouth, but it’s very easy to refill through the side opening, you don’t have to pull apart the entire thing. I also use it while in the shower - this way I can be as messy as I want. My husband uses it with his mouth closed :) Hope this review was helpful!
