Is a bag a gadget?
I bought a big diabetic travel back with a cold pak from the diabetes store, and frankly it just wasn't big enough.
Had a gift certificate from Amazon so broke down and finally brought a Pump Pak. Wish I had years ago! It's Very nice! Very big and much better made than the Medicool bag.
If you want your own, you can get it here -- yes I get a referral fee.:
