    Great read. Would like to know how long the frio stays cool enough for insulin

    Hi Vicki,
    These units work by the evaporation of the water from the gel. When we place an alcohol wipe on our hand(s) it will feel cool as the alcohol evaporates. The website is very helpful. The speed that the gel returns to the solid crystals is dependent upon the temperature and the humidity. I have had the mid-sized units remain in a gel like state for over six days. Again, it is the temperature environment which you are located. As always have a great day.
