“This is an amazing product. My dad recently went on vacation in Cancun, and this pen was a life saver. It kept his insulin safe and cool, even during the day trips in +90F temperatures. It’s easy to carry and gives you peace of mind on the top of being very user friendly and effective.”

“I was a little skeptical, but I've had trouble carrying Humalog pens with me for use while traveling and eating in restaurants. But this technology actually works to keep the insulin at a safe temperature in my purse, without bulky and melting ice packs. It's convenient and compact. You can put the Vivi cap over a pen needle for even more convenience. They are expensive, yes, but how much will an overheated insulin pen cost you? Highly recommended.”

“Discovered this by chance and got it for my recent vacation to Hawaii. It worked perfectly keeping my insulin at safe room temperature even when I was the entire day out at 90+ F. Didn’t had to bother with ice packs that freeze my insulin so often. And when I wasn’t sure about the temperature, i clicked a button on the device and got the green indicator on for few seconds to tell me that I’m good to go. Love it, easy and efficient. I give it a 5 star.”

“I was skeptical about this insulin pen cap but got it anyway because I keep my pen in my diabetes stuff bag and was worried the insulin may get warm. I put my pen in the cap, heard a little click and put it back in the bag. A few hours later that night, I pulled the pen from the cap and it felt cool to the touch. It works and I Absolutely love it!”

“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.”

“I've asked my nursing professor about this product. She s in fact using it and highly recommend 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.”
