Query: All re-inflated

C'mon! Whoever said that those of us who have had problems "wasn't reading the instructions..." etc...baloney. I bought several bags, several sizes, two different stores, different days...followed the instructions TO THE HILT. Many times. Every single bag has re-inflated.Since they apparently sometimes work, my conclusion is that their quality control is lousy, wih some bags being better than others. If that'sa risk you're willing to take, so be it, but save your receipts.
