Not as powerful as my waterpik, but a good enough job to floss at work or on the go

No USB-C = HARD PASS.

I have so many of these and I refuse to buy any with specialized chargers at this point.

Have two of these from similar deals over the last year+. Have to agree that the pulsing power is just ok at best. Never had a water pik, but as popular as they have been for decades, they must be significantly better. The cordless Water Pik gets up to 75psi, no idea what this Coslus puts out.
