I absolutely love my VIVI caps! I absolutely love my VIVI caps! They have taken all of the stress and worry out of keeping my long and rapid insulin safe no matter where I am or what we are doing. I have had them for a year. They have kept my insulin safe in below freezing temperatures on the mountains of Colorado in the winter as well as scorching hot (110 plus) temperatures during the summer in Texas and Oklahoma. I recently bought 2 more so I can take extra insulin on long trips. I love the new design with the clear caps! It is a great improvement on an already wonderful product. I also love how easily they fit into my small crossover bag, purse or backpack. Thanks for giving me the freedom to go anyway and participate in all kinds of outdoor activities without worrying about whether I will ruin my insulin pens.

No worries about Texas summer heat I'm thrilled with my new Tempramed VIVI Cap for both my Novolog Flexpen and Tresiba FlexTouch insulin pens. This is really amazing technology that's so easy to use, and I don't have to think about ice packs or priming cooling pouches with water before I go out. With the temperature over 100 degrees for the past month, and several more months of this heat, I don't have to worry that my insulin will go bad. It's great!

Great Product! My father has been a loyal user of this product for a few years by now, and he absolutely loves it. He particularly appreciates it's ease of use, as it functions effectively without requiring any additional effort on his part. Given the daily use, this aspect of convenience is incredibly significant. Truly deserves 5 stars!

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
