I bought this as a spare because my more expensive flosser keeps breaking down. It almost immediately became my daily driver and the other flosser has become the spare, although it'll probably stop working like the others I bought so I think I'll stick with Coslus waterpiks as they are a 1/3 of the price and I really prefer the power and features on these ones. I guess I'll have to buy another Coslus to replace my other brand that's my spare lol.

Weighing just 237g, the C51 features a lightweight, easy-to-hold body and a removable 300mL water tank. Its 800mAh battery provides up to 21 days of use and fully recharges in approximately 1.3 hours, making it practical for both home and travel.
