General Medi Instant Ice Cold Pack (4”x 5.5”) – 8 Packs Disposable Cold Therapy Ice Packs for Pain Relief, Swelling, Inflammation, Sprains, Toothache – for Athletes & Outdoor Activities

Wow, the cold is really instant! I got about 10 minutes you could really call cold, 20 more of cool until it was all done. This will be a nice item to whip out of my bag if someone gets overheated. Sure, I wish it was a little lighter and stayed cold longer, but such are the constraints of this size and price point.

it is okay but not the best, in my opinion does get too cold, and lose its effect fast , size is good for wrist, hand, ankle and foot. give a temporary short pain relief

I have endometriosis and migraines I use I've packs daily in abdomen and head but I needed something I could use while travelling abroad etc These are now part of my tool box and for the price it's a win They stay cold for a good enough time 10 solid mins 15solid mins I'd say Shake - Fold - Shake

Instant coldness when squeezed, however doesn’t stay cold for 10-15 minutes as stated. I would say more like 5 minutes if that.

work good for roughly 20 minutes before it cooled off. Good for short time injuries
