Product can be used for shorter duration of travel Post gr8 customer service provided by Ms Alina, Im changing my review. She kept a constant follow up and made sure that issue is resolved and product gets delivered to me. I used the VIVI Cap, its a bit helpful but not keeping the temperature that an insuline supposed to at. It just maintained around 26°C (while I was sitting in office where AC was on) for 2hrs whereas the required temp is 15° to 20°C. Its good enough for travelling for shorter duration specially if driving in hot weather. Therefore, 3 stars for Ms Alina and 1 for product. Perhaps company can work on to improve their product.

I saw an ad about the tempra med… I saw an ad about the tempra med product on how it prevents your insulin from spoiling or get ineffective because of heat. I was skeptical about it but still bought myself 2 of the item. I am glad I did because it does work. I forgot my insulin bag in the car, under the midday heat of the sun. I was horrified by the thought that I just wasted to 2 different insulin. When I got the bag I was genuinely surprised to find my insulin pens cool as if it was in the refrigerator. I was happy about this that I already recommended the product to my friends who use insulin pens.

VIVI Cap — Look no further I recently started using insulin, and was going on a trip requiring something to keep my pen at a proper temperature range. After much research, I found the VIVI cap. It proved better than I imagined!!!! Easy to use, required no freezer packs, or charging. Perfection — my insulin did not spoil!!! Buy one you won’t regret it.

Doesn't wet items in my bag Doesn't wet items in my bag! The vivi cap is awesome because the other ways that I've been keeping my insulin cool involve ice packs or wet packs that often get other items in my travel bag wet, soaked, or damped. No water is involved here and that's terrific!

One of the best buys I’ve ever brought One of the best buys I’ve ever brought. The constant stress of carrying insulin around on holiday has always impacted my mods when being in the heat. With the cap it takes away every little bit of stress allowing you to enjoy every bit of your holiday, no matter how hot it is
