FRIO DUO Insulin Cooler Wallet - Keep Medication Cool for 45+ Hours Insulin Bag - Perfect for Travel and Everyday Use

I bought this product for my teenage type 1 diabetic son. He needed independence and this gives peace of mind. It does not leak! I read a review stating it leaks. After recharging with water and only while it's wet in the water their may be a very slight film on the water. It's likely from the gel beads, but to claim it leaks is ridiculous. It's much better to chatge every 2 to 3 days if you're going to use it continuously. My son often forgets to recharge with water and the beads get dried out if you do this. This little bag is amazing! It keeps 2 pens perfectly (unless you overcharge!) If you do overcharge be sure to put medication in with the lid on top sliding pen in with counterpart first. This way you don't have to try and get a lid out! This only happens that the fit is too tight if you leave in water too long. The learning curve isn't that hard. I'd recommend using a timer. Start with 2 minutes per side in cold water and continue flipping until product feels full. It will literally puff up! First time or after not using for a while takes longer to charge. Love this little thing! Now if only they made them specifically for epipens!Not to people who don't understand the concept os this bag, it keeps your medication at room temp! Once insulin is removed from fridge for use this is recommended! Nobody wants to put refrigerated insulin in their body! It can hurt/sting. Also remember it's perfectly safe to store your insulin at room temperature and use for 28 days! Some people write reviews complaining this product doesn't keep their child's insulin at 45 degrees. It seems they don't understand that's just when refrigerating for long term storage that u have a max temp of 46. Personally I keep our insulin in a seperate mini fridge and store around 40°. Recommend Temps are 36° to 46° F or between 2-8°C. That's for long term storage!!!This Frio wallet is for daily storage at room temperatures! Room temperature storage is between 59° to 86° F or 15° to 30°C . This keeps it perfectly in that sweet spot even when in the heat when used properly! Sweet spot being 20–25°C or 68–77°F! Incredible product.

I must admit that I was skeptical that this would actually work as described, but simply put, it does and I love it. I bought this because I fly a lot and didn't want to deal with products with ice packs, especially going through TSA (I know ice packs are permitted by TSA for medicine but the process can still be a pain). This is much more convenient and compact and keeps things cold for several days (not hours) without refrigeration. There is no melting or sweating of ice packs to deal with and you don't need to worry about ice packs that can freeze your medicine. I have been using it since November, and it worked for all of my trips without an issue (even to several hot locations in the Caribbean). Simply soak the interior pouch in water, lay it on a paper towel to soak up any excess water, slide your medicine in the pouch, slide the pouch into the outer case and go. The product has some type of crystals in the interior pouch lining that swell when soaked in water and turn into a gel like substance. When you are finished using it, you just let it sit out and air dry and the gel turns back into crystals. It is so simple, convenient and reusable.

I have used Frio cooling cases for years and they work really well. They are made to keep insulin cool but will NOT keep anything cold, at refrigerator temperature nor frozen. Insulin is supposed to be stored long-term in a refrigerator but an open bottle or pen should be kept at room temperature or slightly cooler. Frio cases use evaporation and work perfectly for this purpose.If you don't follow the directions the case won't keep anything cool so I will do a quick re-cap of the directions for anyone who might have lost their directions.Remove the inner case from the Velcro-close outer cover. Place the inner pouch into a sink and fill the sink with enough water to cover the pouch. Allow it to absorb water until it is nice and puffy but not rigid, usually about 10 minutes. I don't set a timer but just check it after a few minutes. If it gets too rigid you can gently squeeze it to remove some of the water. Drain the water from the sink and let the pouch sit for a few minutes, then wipe lightly with a towel. Place the insulin or pens into the soaked pouch and put all of that into the cover. This will NOT leak! DO NOT put it into a Ziploc bag or other plastic.The really important thing to remember is that this works by evaporation so air needs to get to the pouch. I keep mine in a loosely packed tote bag or a purse, or on the car seat. Don't pack it into a suitcase or tightly closed bag because it won't work. I'm not sure if this will work on hot summer days when I need to leave my insulin in a closed-up car for several hours so I will put the whole thing into a cooler with some ice packs. The padded pouch protects the insulin from freezing against the ice packs.I have never had one of these stop working so I don't know how long they can last. I usually end up losing mine and having to buy a new one.

This works as described, keeping the insulin pens cool. Please note this isn't a refrigerator, so it's not going to keep anything cold. It's designed to keep insulin at room temperature, which is in the 70s. The only reason I'm not giving it a 5 star review is because I don't think it will last long with continual use. The material and stitching is not heavy or durable enough to withstand continual use. This may be due to the need for it to be porous enough to allow evaporation, but with current materials technology, I would think there would be a way to make this a little more rugged.
