Ever Ready First Aid Disposable Cold Compress Therapy Instant Ice Pack for Injuries 4.5" x 7" - 24 Pack

Price is cheap.Size is ok, enough for normal use.Good for relief pain when injure.

I am an on-site medic at an outdoor entertainment center and I use these in my EMT pack. They are pretty easy to activate, and the temp on them when activated is perfect WITHOUT WRAPPING it in a towel. I use them without towels and it works great. They only last 5-10 minutes though.. So I would only use it to treat an injured person. Don;t worry about puncturing the bag when activating it. It would take some sweat to rip these bags

Bought these to add to my emergency kit. Tried one and it works perfectly

This product does not stay cold very long. I've used others that are a lot better.

I had to use one of these for the first time this weekend when a friend fell and busted her nose at a restaurant. There are a couple of things that I realized. First, it takes way too much pressure to rupture the inside pouch. I was squeezing so hard, I though I would pop the outside bag. If you don't have a lot of hand strength, you will have a lot of trouble activating the pack. Secondly, even worse, it didn't get very cold and only lasted about 2 minutes. It's pretty embarrassing when you go to help someone and you have to keep apologizing for your gear. I ended up asking the restaurant staff for a towel and ice. In an emergency, you need to have supplies and equipment that you can rely on. This is not it. They have a good rating but I'm not sure why. Save yourself the frustration and buy something else.
