Query: Insulin - Byetta cooling

Have not used this as yet. Read many many reviews on the internet before buying it. I keep it on hand should I need to venture where ice is not available. Currently I use a brief case size thermous where I can roll some small ice in a zip loc and roll my injectable pen in bubble wrap and put it alongside the ice in the thermous. This will keep for a full day. The bubble wrap keeps the "pen" away from the ice so it will not freeze the contents. I am on Byetta and once it is opened, it must be stored below 78 degrees and the Frio cooling wallet is supposed to do that. Very many testimonials on the internet from hikers and bicyclests that believe in the Frio.
