I purchased it for my son, so his insulin is kept cool while he's outside. It's very convenient since he does not have to do anything !:) It is really small, sits inside his bag and when I checked it, the insulin was cool. Keeps him safe and that's what matters.

“I've studied the cooling bags and when I learned about this one, I was skeptical. The cooling bags did not work for me, is this one any different? Well, the short story is that it works. If you continue reading, you'd find out why I say that. First I've measured the temperature of the insulin with one of these infrared thermometers. When it was 110F outside the insulin was at 81F ! that's below the limit of 86 and it stayed like that for hours! Second

I've asked my nursing professor about this product. She is in fact using it and highly recommends it. Just replace the pen cap with this one and you're good to go, nothing else to do and the insulin is kept cool. This can stay on your pen since it is very small and doesn't take space.

I have been a diabetic my whole life and the effort that it takes to carry around my insulin and ensure that it is kept at a safe temperature can be a difficult process. My parents recently bought me the MY VIV CAP to make transporting my insulin a lot easier to manage. I can now just keep my insulin easily in my pocket or work bag. Would highly recommend this product.

"Basically replaces my pen's cap and keeps my pen in a cooler, steady temperature. Easy to carry in my purse and I love the fact that there is no need to do anything like replacing a battery, charging and putting in the refrigerator over night"
