Review on 🚿 H2ofloss Cordless Water Dental Flosser - Portable Oral Irrigator for Teeth, Braces | Rechargeable, IPX7 Waterproof Teeth Cleaner for Home & Travel by Katie Jackson

On the advice of my dental hygienist I purchased WaterPik floss over 5 years ago. I chose "portable" as I don't have room for a giant WaterPik. That worked fine for a while. but the water tank was VERY loose - you had to balance the unit "like an ice cream cone" or it would fall apart in use. The first block got black mold over time, so I bought a second WaterPik. The same problems. So my third floss was the Zerhunt Cordless Oral Irrigator - better than WaterPiks, but after a while: black mold inside. This 4th module is the best of all. The tank snaps in place and is great for cleaning your teeth BUT TWO NOTES: 1. You MUST purchase a separate AC/DC USB charger. The device inexplicably doesn't have one, so you won't be able to charge it when it arrives. 2.AIR DRY the reservoir and spray the device with "empty air" after each use, otherwise black mold will ruin the device over time. I keep the container tipped over a folded paper towel each night and run the unit for a few seconds after each use to "empty" the water. Of course: I wash the exterior of the device with soap and water before drying it overnight. Conclusion: Best in class, but hygiene before and after use is crucial.
