Bests & Worsts Reviews from Amazon

My family first started using these several years ago, on the advice of a friend. My mom and I both suffer from extreme ear pain when we're in an airplane during take off and landing; that change in pressure is horrendous. The pain was bad enough that it made me seriously dread any flight. After I started using these earplanes during take off/landing, the pain disappeared! I put them in while we are on the tarmac. Once we are at cruising altitude, it's not a problem and I take them out until I hear the announcement that we are preparing to land, and I put them back in. I was so impressed that I bought a pack of them for my mother, who had even more pain than I did, and after her last flight to come visit me, she happily reported no pain whatsoever with these magical ear plugs. There is a little ceramic ball inside the plug that somehow keeps air pressure more consistent. Just to be clear, these are not the type of ear plugs that you'd use to block out noise; they are specifically for reducing the painful pressure changes associated with flying. The directions on the back state that each pair is good for a round trip flight (meaning two plane rides). I have definitely reused a pair multiple times without any issue. I'm not really sure just how many flights they will last, so usually after 3-4 roundtrip flights I switch to a new pair, just to be safe. Let me know if you have any questions. If you found my review helpful, I'd appreciate it if you consider leaving me feedback!
