Just a comment; the extra 20% didn't work initially. I deleted the item from my cart and went to buy it again and both discounts were applied. Don't give up after one try if you don't get the discount.

Most of these end up broken and unrepairable. Eventually it's just landfill food.

Some are much quicker than others though. And some things aren't plastic and batteries.

Of all things to take a stand on when it comes to waste > a potential solution for flossing

Is flossing really that inconvenient?

Landfill *food* lol. Interesting way of putting it. You must be a politician.

Reminds me of things like "Vegan leather" and even dumber things like "no animal testing" (yeah, because it's being tested on you humans).

You didn't need this to floss. There is no credible evidence that it's helpful compared to regular flossing and brushing.

Yeah actually some people do need this to maintain dental health and there are tons of folks with dental prosthetics and implants that you actually DO need to use this. Just about every thread some smart person with a limited view of reality feels the need to spread their small minded ideas on the rest of us..

Some if us have teeth so tightly spaced especially at the top that it is actually almost impossible to get floss between them and so frustrating you give up. Thus the water flosser is a teeth saver.
