I purchased two QuickBreezes in 2009. I use mine daily, and it is still in use after nearly 13 years. My QuickBreeze's valve has just recently started leaking slightly, so I am going to purchase another QuickBreeze. I think it's amazing that these devices have had such good longevity. Oral Breeze did replace a few tubing parts for us once, but still. It's a shame that QuickBreeze's Amazon.com score is so mediocre and that a few bad reviews are displayed very prominently. That's unfair and unrepresentative, in my opinion, unless the quality of the product has changed a lot since 2009. I travel with my QuickBreeze occasionally, and a number of hotel and friends' faucets now have cleaner faucet aerators as a result. Whenever I replace one of these aerators temporarily with a QuickBreeze adapter, I clean off the aerator's little particles. I've noticed that hotel maids don't recognize that anything's different when I replace the hotel bathroom's normal aerator with a QuickBreeze adapter temporarily, so I normally just leave the adapter in place during the day while I'm away from the room, and I haven't lost a single adapter that way yet. Thanks for inventing this clever device, which has benefited me and my family consistently over the years.
