Arizona Ice Large Industrial Ice Packs | Replaces 10lbs of Ice |18°F (-8°C) | Deepest Grooves | May Freeze Drinks | USA Company | 12" x 9" | Two Pack

Awesome product. Handle makes it easy to transport. Large size lays in bottom of large cooler, or stand up along the sides. Keeps items cold all day with no melted water to get into your food items. Thin enough to fit in hotel fridge to refreeze nightly. I use two in a large cooler and they last all day. No mess, no melted water to slosh out or have to search around in.

Last summer I was the main food carrier for 16+ people for 3 days on the river. The first time I used these I thought they were a waste of money because they didn't keep everything fully cold all weekend. The second time I got smart and paired them with ice. At the end of 3 days, there were still fully intact pieces of ice and everything was really cold. I depend on these in the summer, they work so well! Must have for anyone thinking about multiple days using a cooler.

The product does just what it says it will. I'm dealing with a 112 heat index where I live and need something to keep my food cool until I get home. I took the lid off, added water, put the lid back on, and shook it until I felt the powder was mixed well. I froze it for 24 hours and couldn't be happier. I put these in my cold bag and added the cold items to it. I am generally in town for 8 hours, so when I say this product keeps my food cold until I get home, it does. It's truly amazing that, as hot as the car gets inside, the ice packs are working. They are still frozen when I get home!!! I do keep them in the freezer at all times until needed, ensuring that I always have them ready. You can't go wrong with these packs!

I use these to keep the water cool in a circulated water cooling system for an electronics project. They appear to store more thermal energy that comparably sized water ice. The ribbed design creates large surface area, in a compact package - this is perfect for my application. They are also much sturdier than comparable ice packs - they can take significant amount of abuse and not crack/stretch. The only thing I'd improve is to have some sort of semi-permanent way to seal the caps, so someone else in the shop does not try to drain/refill them with regular water. I appreciate that someone really thought through the design on these.

Pretty impressed with these. I put just 1 into a insulated soft case cooler with a towel to protect the produce I took to camp for 6 days. The case was still cold on the 4th day. And by that time my produce was down to the last items that didn't need to remain really cold. Weather warmed up on those last days so it held up real well considering it was just 1 pack and a thin soft case cooler. I have yet to put these to use in a camp cooler for a 5 or 6 day mission. I rely on 2 large (80+oz) juice containers filled with water and frozen solid. I need ice to last a week or longer while I am out in the mountains. Not quite ready to try these for those longer missions. During the winter, these should perform quite well for keeping the cooler cold for 5 or 6 days. These ice packs have been useful for shopping. Take up little room in the cooler. Kept food items cold during summer shopping missions. And with the cost of food... its totally worth the effort and time to make sure items stay cold till you get back home. As I continue testing these I will update as the year gets closer to its end. My hope is that I can use these for shorter camp missions and maybe 5or 6 day missions during late fall/winter.

I really liked these the only reason I didn't give them a 5 star is because one came dented a little but I won't complain much, now to the good part these get fairly cold with in 8 hours better if you leave them over night in the meat freezer.... first time I used them alone they cooled for about 24 hours and then didn't..... so I experimented and cooled off the cooler in the house and then made sure the drinks were cold as well when placing them in the cooler.... they work best with some ice around them..... alone they aren't life changing but with some ice you will see they keep even the water cold enough to turn into some ice..... they are well worth it, they look solid and I have yet to have any issues, they work well in ice water as well I noticed that with these my ice will last about 4 days with out the ice might melt by day 2.... and there in the houston heat I very much liked that they are thin and fit well in the fridge. These are good for larger coolers and may not fit in smaller coolers.

My nephew and I were a long way from the road doing outdoor activities. It was hot. 96 degrees and humid. Feels like 106. He is a large man. 340 lbs plus. He stopped sweating and began to have a heat stroke. I had one of these ice packs in a light weight cooler we packed in. I poured water over his head and neck and gave him this ice pack to put under his shirt and hug against his body. In about 15 minutes he began to recover. The pack cooled his internal body temperature back down to a safe level. We put the pack back in the cooler and it still kept the drinks cold. This is a life saver. Literally. I had some frozen water bottles in the cooler too…. They didn’t thaw until we took them out. Being a first aid device was not on my mind when I purchased or packed this. But it is a first aid lifesaver.

I’ve used these for over a month and really pleased with them. Once you do the relatively simple fill and freeze setup according to the instructions you have quite good quality ice packs. Everyone’s going to have different times that these packs will keep cold but I can get 24 hours and then some. So with that these do the job well for me and my uses in a soft cooler. Fits well and seems like it will hold up for many times over. Supplementing these with ice will make both of them last quite a good chunk longer and colder so if you can or want to do that, it’s helpful to keep in mind. I use a smaller different hard pack with these just to replicate a bit of the same regular ice effect though. Works fine enough for me. Would recommend these packs if you’re needing good quality and long lasting ice packs I think it would be hard to find any much better.
