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.

I bought my first water flosser almost a year ago and I thought it would be enough to replace normal flossing. I was very wrong and wish I had just kept my normal flossing routine.

I've recently noticed degradation in my overall oral health as I now have cavities between my teeth even though I have brushed and used the water flosser daily. I've now added normal flossing after the water floss and the floss still picks up bits of plaque. So a word of warning to anyone thinking this will be enough to replace normal flossing — it won't.

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?

Are you trying the code on a white one? It doesn't work on black but I bought 2 white ones with that code.

good price, but these portable ones just don't have the capacity. I usually have to fill it three times.

These were originally branded as "Only P", but they were forced to relabel after it caught the attention of procter & gamble's legal department

That is a drawback but it makes them great for travel though. Also please note that these are randomly USB-C and proprietary charging port. Mine was white and USB-C, but others have reported getting a figure 8 charging port on theirs (on previous deal for the black color I think).
