Works very well, but read and follow instructions
I've used this large, cooler wallet a few times, and it's worked very well, keeping my regular insulin cool as I travel to conferences with my diabetic supplies. It does not keep the insulin quite as cool as in a refrigerator, but significantly cool enough (have not actually measured the coolness with a thermometer). It's definitely necessary to read and understand the directions before attempting to use it, because it's possible to damage or break it (excess swelling from too much soaking or not spreading the crystals around evenly). My experience is that the coolness lasts 2-3 days, during this Fall season. I personally would not subject the cooling wallet to temperature extremes, either cold or hot, for best results (IMO). Because the instructions state do not put wallet in refrigerator, and because other Amazon users have left the cooling wallet in a closed car on a hot, summer day (IMO, pushing their luck?).

Stupendous prduct
I bought htis recently for my parents and find this very useful. This holds cool for two days (believe me.. 48 hours full) despite out heat beat trip in our car. Amust for anyone who wishes to keep medicines cool and stable. I will recommend this for anyone.

I have traveled the world
I have had nothing but good luck with my Frio. It has gone with me to Britain, Italy, and in the next few months will accompany me to Poland and Greece. I have also taken it camping with me in the North Carolina summer heat without any problem at all. It has always remained cool inside, regardless of the outside temperature, for at least 48 hours (usually longer) before I have to recharge it. It is now four years old and, while it takes a bit longer than ten minutes for the initial charge, still working as well as before.

It works.
I've used this wallet in high temperatures. Keeping it inside a hot car with windows rolled up during very hot days. The inside of the pack always stayed cool. Been using it daily for around a year now. I don't use it with the outer cover though.

Very unhappy with the high temp performance
Used as directed and lost 3 pens when the temperature hit 100 degrees. Foolish me, I kept thinking that the error was mine. We had a small and a large pack. The small pack was essentially worthless, the larger pack seemed to be large enough to keep for for last for a few hours. Works great as long as the temp doesn't go much over the recommended maximum temperature for your insulin and/or you keep it cool by adding some kind of ice pack. If you're expecting the answer to having to carry around all the stuff...this isn't necessarily going to be it.
