My AirFloss can be attributed to better check-ups at the dentist office. It definitely does what it's made to do. A couple of the drawbacks are ... the holding tank should be just slightly larger and the absolute worst complaint is the cheap clear plastic lid for the holding tank. Mine has popped off numerous times and if one of those little pegs get bent, smashed or falls off, it's all over ... you may as well toss the entire product. You can't keep water/mouth wash in the reservoir with no lid.
This is my first time trying this flosser after using waterpick for years. it does the job well, but sometimes seems to be a tad too strong. If you point it slightly off it may cause a slight bleeding of your gums. Nothing drastic, but may scare someone off. The best thing is that you can floss with mouthwash and it covers both cleaning and rinsing. design by itself is ergonomic, easy to hold and clean.
I've had. 4 air floss products. I like the design and performance. The down side is the life of the product. The last replacement I bought only lasted 3 weeks. Support group is excellent and have sent me a replacement.
The first unit we bought through our dentist and loved it, but it developed an issue. Called the company and they replaced it with no hassle. Not many companies would do that these days.
