Proprietary charger end to full size USB cable. Trying to replace a similar model for that difference alone. I have two others for kids that are USB C.

I've had an old waterpik for a while. Pretty annoying with the wires, I've barely used it at all. Hopefully the convenience here will get me in a better habit. Price makes it a no brainer for me.

Surprisingly powerful - had mine for 4mo, and can confirm it's a game changer. No more wrestling with the coiled hose on your Waterpik.
