Freez Pak Medium Extra Cold Reusable Ice Pack with Hard Shell 2.85 lbs, 8.5 Inches

They stay frozen so long that it is awesome. They lasted me about 24 hours in a sealed cooler. I consistently take ice cream from one place to another and they always keep it as cold as it was when I put it in. I'm loving them and will get more when I get a second cooler

These Freeze pak Extra cold stay frozen for about 24 hours in my cooler. I put 2 along the bottom which fit exactly in my 32q cooler. The handle on the Freeze Pak is so convinient.

this Freez Pak worked so good i had to buy another one. it stays cold for days. it's so cold my hands starts to burn after a few seconds. an example of how cold this thing gets, my soda would turn a bit slushy inside which makes it taste 2x better. try that with beer and you'll know what i mean. i also tried their Small Bag Ice which sucks since it'a soft shell bag, it starts leaking. this one is the hard shell which is more reliable and last a long time.

Keeps stuff cold, takes a few to keep a large cooler cold for multiple days. Won't last very long if you don't pre chill your cooler or if you put anything not already cold in it with them. They aren't too cool things down, they are too keep them cold by maintaining the temperature. If used as intended they are great and will stay for days in a decent quality cooler.

great for keeping a cooler cold without the melted ice mess at the end and avoiding grabbing wet bottles and snack packages for use during the trip.

only time will tell after months of daily use. I got a new cooler to so it seems to keep drinks cold for more than 8 hours

I guess it's my fault for not reading the very fine print to see the exact size of this thing.. but I bought it for my evaporative air cooler and it's WAY too big for it. I can get it to work and fit in, but I have to take the whole thing apart and it's just a big hassle. I just wish there would've been a picture to show exactly how big it was so I would've known! I still use it though and I do like it! It's just a hassle when I'm feeling lazy or I'm in a hurry.

Not pleased at all it was a gift so that's why I waited so long to write review. It wasn't used when I first received it. I don't know if I can return it or get a replacement or refund but they leaked blue stuff all over lunch items that I was too scared to eat my lunch.

Defective, leaks blue chemical. Not recommended. Was using in the refrigerator and worried about contamination of food.

It needs to be modified needs a cap or something because if always leaks for that spot 2 of the ones I bought leaked after a day
