Rated 1 out of 5 by from It fails after 6-8 weeks of use I am now at my 3rd new unit in less then 6 months! My very first Airfloss lasted for over 12 months and it would not charge. I bought a new unit and after less than 6 weeks it failed and l got it replaced. Same thing happen again and l am now at my 3rd new unit. I like the product, l am using it every day, l use mouth wash , Colgate Whitening or Listerine to floss instead of water because of advanced gum disease. I used the product the same way everyday, l don't immerse it in water after use, just whipe it clean, not sure what to do next, the new unit l got 1 month ago failed tonight. Please help

Rated 1 out of 5 by from very dissapointed with this product had this product about eight months when it started to go wrong when it was on the 3 setting it kept making a funny noise and cutting out, I never bothered because it still worked on the single water jet. but now just before Christmas it has packed in completely I understand the warranty is up but I am very disappointed with the product, I have purchased a new one for Christmas, but noticed the 3 button model is not available am I correct in assuming that there was a problem with this model in which case should there not have been a recall.

Rated 1 out of 5 by from great product but ................................ You will not want publish this but the feedback might be useful A great product - does exacltly what it should - until it fails I HAVE HAD SIX OF THESE UNITS! 4 of them had some sort of motor failure that sounded an alarm - The response was great - replacements supplied. I purchased a 5th unit rather than ask yet again for a replacement - it failed in a different way - intermittent battery connection - perhaps a dry joint - again no problem about getting a warranty replacement - full marks - remains to be seen whether the original problem has be solved and this was an isolated case

Rated 1 out of 5 by from Previous model better I bought the HX8340. Absolutely gutless, cannot feel anything between the teeth. The nozzle is bad design, it flares out and your teeth gets washed, not between. HX8140, green nozzle best one I had, powerful and a needle like nozzle that actually targets and blasts between the teeth. Sad part about the new model is that the nozzle is not Interchangeable with the green nozzle which may solve the problem I am having having, not getting the blast between the teeth. Triple burst feature is great but the nozzle doesn't allow you to experience its performance.

Rated 1 out of 5 by from Not very good This product did not live up to the hype given to it. The Water Pic does a better job, as this one didn't always dislodge any bits left in between teeth after brushing. I was very disappointed. It slipped out of my hand into the wash basin, not a great distance as I was leaning over the basin, and is now broken. It wasn't good enough to make me purchase a replacement.

Rated 5 out of 5 by from Our orthodontist is very happy about this! The trouble with floss is it’s awkward, it’s messy, and it only cleans between the teeth (but not all around the gums). This product on the other hand, is easy, convenient, and cleans all around the teeth - including under orthodontic wires! We had the basic model until the battery eventually gave out (about 4 years, even though it lived on the charger 24/7, contrary to instructions), then upgraded to the ultra this time around. No regrets about the extra money - totally worth it :-) Tip for everyday use: We bought a squeeze bottle from the supermarket. Pour in one cap full of mouthwash and top up with water. Use this for no-mess refills and fresh minty aftertaste!

Rated 1 out of 5 by from Disappointed I thought this item would have a continuous flow of water but it doesn’t. It just has bursts of water. It’s also very noisy. I couldn’t return it to shaver shop once opened so I’m stuck with an expensive item I’m not using.

Rated 2 out of 5 by from Replaced by 2 weeks Product only lasted 2 weeks . Store offered to replaced the product but gave me thr wrong model. It took couple of trips to the shop to get the whole thing sorted out. The store staff advised me to go with another brand next time. It turns out a number of people has been complaining about the quality of this product. Its compact and easy to use, comes wirh 90 day warrant. Hopefully product last more than 90 days.
