Review on Portable Water Flosser, Teeth Cleaning Water Pick with 3 Modes & 4 Jet Tips, IPX5 Waterproof Dental Oral Irrigator with 2 Minutes Auto-Timer and Travel Bag for Office, Home, and Travel use (Black) by Max Stallworth

I was skeptical at first, but it does the job. It takes a few minutes to understand the correct technique. Otherwise you leave a big mess. Make sure you keep your mouth shut or water will splash everywhere. It's pretty strong too. My gums bled a little when setting the pulse because I was aiming too low. Now I only use it for the bare minimum. I don't think it matters, but I fill it with purified water so it doesn't get clogged with scale to be on the safe side. I was very surprised how much dirt he removed from my teeth. My only complaint is that the water tank only lasts for one use, which isn't too bad. The replenishment only takes a second.
