Before you buy this remember you get what you paid for. If you look at the reviews in the last couple months sort by recent reviews you will see a lot of negative reviews saying it stopped working and one review said their caught on fire. I recently bought the sonicare name branded flosser and on sale it was $99 for 2 of them. This look exactly like the name brand. But just even based on the one review their caught on fire I would steer clear of this.

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.

Seems to be just a deal for $23.88, and promo code is no longer working. If that changes, would love to know as I've been hoping for a deal on this!

I got this on the last $9.99 deal and I've honestly been very happy with it. I've never used an actual Waterpik or anything but for the price I don't think this can be beat. Consumer reports gives it a good rating too.
