Sonic-Fusion 2.0 Professional Flossing Electric Toothbrush with Water Flosser Combo In One, White SF-04, Packaging May Vary

I had one of these and loved it. I even rave about the product to my friends and bought one for Christmas as a gift for one of my best friends. It ended up being a mistake with plenty of consequences. The unit didn’t work, and after several attempts of investigating it once she turned it over to me, I found that the base unit and the toothbrush don’t match IDs, so the highly touted wireless connection didn’t work and would never work since they are tied to the unit’s ID. This careless mistake on the manufacturer’s side meant I was forced to take back the present and return it. I had to then personally repack it and bring it to the post office and pay $66.60 to ship it back. Amazon is only going to reimburse me for half of that, and only weeks from now. Terrible service on both Amazon’s part (I’ve always been able to get returns picked up but they don’t offer it anymore) as well as Waterpik for screwing up in the first place!

TLDR: If somehow the flosser doesn't respond to the toothbrush's signals and the radio and toothbrush resets don’t work, drain the toothbrush's battery completely by setting it idle for a week or so and reconnect the set to power. Make sure you place the toothbrush in the base before reconnecting the set to power. Waterpik offers great customer service and the device works great and does what it's supposed to do most of the time. ----------------------------------------- I bought one 2.5 years ago, and after less than 2 months of using it, the flosser stopped responding to the toothbrush's command. I don't know how it happened but I knew it was a housekeeper who unplugged the device as he had to clean the counter. After a few days of testing the flossing function and trying the troubleshooting techniques without success, I gave up and contacted Waterpik's customer service. They asked for anything, you know, that would allow them to honor the warranty. The process was a bit annoying (just a bit, and is absolutely nothing compared to arguing with insurance about coverage) but Waterpik in the end sent me another set for free which I'm still using today. Being the environmentally conscious and lazy person I am, I kept the first set because it'd be a chore to dispose of it properly, so I just put it into the original packaging and stored it in the vanity cabinet. Last year, I had to move to another state and while I was packing stuff up, I saw the set and decided to give it another try before completely throwing it away. And it xxxxing worked!!!!!! Now that I commute in between cities, I've placed one at the residence close to my workplace!!! Also I've been periodontitis free for the past 2 years! Thanks Waterpik!!

Me gusto todo

Truely believe the product is a faulty given a large number of reviewers came back here with the same issue with wireless water flossing after a few months of use. I have contacted Amazon to contact seller for warranty services or compensation, if any. Will be back to update here upon their response. Update: 24/01/2023 got a auto-reply from the system that the seller of my unit is no longer Amazon, so I am not able to ask for further support. Will face a dispute under Australian consumer law.

Love this product-- per my hygienist and dentist, it has improved my gums and almost completely eliminated plaque build-up. It makes brushing so much easier, too. One caveat: DO NOT buy cheap replacement brushes to use with this. I tried an off-brand replacement brush as they were cheaper, but the brush became permanently locked/fused to the brush arm. I tried many customer service and YouTube suggestion-fixess with no change, so I'm now buying a new device. My previous Sonic brush-flosser last 2+ years, so I can't be too disappointed. Only Sonic-Fusion brush heads for me from now on!
