I test out the cheapest water flosser on Amazon for $9.99, from Bafovy, a brand I’ve never heard of. I previously tested the Waterpik Waterflosser which costs more than 3x as much. But in my testing, the Bafovy cleaned just as well, has a built-in rechargeable lithium battery, and collapses to less than half the size of the Waterpik.
The Bafovy has a compact travel design, similar to the Panasonic portable flosser. The clear plastic reservoir sits below the pump body and telescopes into the reservoir when packing for travel. The unit charges with a proprietary USB-A based charging cable.
The strength of the stream feels comparable to the Waterpik but the unit is operated via button rather than a slider/switch. The unit has 3 pump pump modes: soft, pulse, and DIY (strong). The unit remembers the last mode selected. In practice, the button operation is a little unpredictable sometimes switching the mode rather than turning the unit off when pressed. This was the product’s only negative quality during testing.
The only potential issue that could not be tested is battery longevity and motor durability, which remains to be seen. But for $10 I’m more than willing to give this product a try. It comes in 3 colors (well really 3 color accents on the button and rim). As I mentioned, it’s available on Amazon though my affiliate link: https://amzn.to/3B72dSG
