yes.. worth a shot at this price but I never opened mine.. I went with a different brand with removable tank for refilling. Good health investment in oral health. and mouth feels fresh. I almost forget to brush when I put a little mouthwash in the tank.

Hey folks - You apparently need to choose Bikenis or whatever the name of the Seller is to use the code.

Decent flosser. My battery died after 14 months and they sent a free replacement because it's covered by a 24 month warranty

Quote from hopeforgood

This product is trash. Power button ( ON/OFF) switch is on wrong position. Dispenser head keeps rotating. Battery life sucks. Overall 1 out of 100 rating.

My wife has been using this one for about six months now and has no problems. It is as strong as the Btivae one I have and holds a charge for long time. They are both much better than the Waterpik branded(China) travel loser I had previously. In fact I gave up on my plug in countertop water flosser.

Maybe you got lemon or something but one bad product out of a production run does not make all products trash or junk. I once paid $28,000 for a Isuzu and it was a complete lemon. That did not mean that the model was bad in general or that Isuzu made all bad products. In fact the model I got was rated well for dependability I just happened to get a bad one. I can state I got a bad one but plenty of other people had perfectly wonderful vehicles and my one experience was not a universal. All production runs and factory lines have failure rates

Works just fine. Like other commenters have stated, you need to select the proper seller for the discount. Side note, you don't actually need prime for free shipping on this. That just gives you shipping a few days earlier. Standard shipping is still free, even without the normal $25 amazon breakpoint.

Can you actually use this in place of flossing? Would love if that were the case, as even string flossers are uncomfortable to fit between my teeth.
