I am glad that someone posted something about these......i have never heard of them. I dont have a problem when flying, but last year on one leg of our trip, my wife was in tears because her ears hurt so bad upon descending into orlando. She said it felt like a knife was in her ear. She didnt have too bad a time on the other flights, but it did hurt a little. When i saw this, i knew i better try some. We went out yesterday looking for them since we leave this sat. night. I found them at Wal-Mart for $3.87 for 1 pair, which states it can be used for 2 flights. I bought her 2 pair and she looks forward to trying them. Thanks again for the heads up!!
