Highly recommended

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.

It works and I Absolutely love it!

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!

Love it, easy and efficient

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.

Scientific & Medical Advisor

"As a clinician and clinical investigator concerned about better treatments for diabetes, the VIVI Cap will be of particular benefit for my patients who require insulin shots, as the vast majority of patients use insulin pens for their daily injections."


Medical Advisor

"Most people don't realize how fragile insulin is, and how to store it for it to work the most effectively. The VIVI Cap is an incredibly simple solution to ensure that insulin is safe to use and that none of it goes to waste"


Medical Advisor

"I was so excited to find the VIVI Cap products. Temperature extremes affect Insulin and once that happens, the blood sugar controls get out of hand. I really think it's a life-saving product. Plus, it's all FDA registered and very easy to use"
