Almost every morning, I must rinse my nasal passages due to dryness and stuffiness, and these are nice enough packets, but I wish they were easier to open (they are in plastic tubes, which do make them waterproof, and mandatory opening them with scissors). However, even for using them, the tube does it make it easier to pour the solution into the bottle for my system, and the pack was very full which I loved, and they were perfect for the price. They do help with my breathing issues, and with congestion, for sure. Also, the size of them is nice to be able to take with me, and they are easy to use, which I also appreciate.
