Query: Life saver!!!! Must have product!!

Amazing product, literally saved us so much trouble!!!! I bought it for my mother (using Victoza), who is usually visiting me from out of the US. She needs to carry her Victoza in coolers during the flight, which causes so many issues - coolers are large and get everything wet, and in a flight of 12 hours it is just a nightmare. Imagine the difference of carrying the Victoza with this small cooler- it was AMAZING! It worked perfectly, my mother used it through the flight and has her Victoza safe to use. It saved us so much trouble, I'm so grateful for this product.
