Review (4/5): Mostly good
Before this I used the electric tank water flossers, and while they work great, I have very limited counter space and hated how much room they took up, so I switched to this. Overall, I really like it, but I do think that the high setting could be a little stronger, it is a bit lower pressure than the tank ones. I had no problem filling the tank and it still does a good job on flossing my teeth. I also love that everything can fit in the nice case provided which makes it great for travel and keeps everything together.
