Dang! This ruins the happiness that many of us had from buying these water flossers at 10 bucks. Just kidding.
Gr8 price. And I personally find water flossers lot easier to use compared to the conventional thread based one, but my dentist keeps telling me to use that one though.

Thread based one? You mean the one connected to the tank?

KZ7B4TOP still seems to work. If you're using the Amazon app you might be missing the step of tapping on the arrow that appears in the promo code box to apply the code.

Same - this is my first water flosser and it's worked great for a couple months now. My dentist told me the same thing, that the water flossers work fine for day to day stuff, but you still want to choose conventional floss intermittently. Like having your car washed by a touchless car wash vs. using a sponge yourself - both do the job, one just does it a little more precisely/better.
