    Wanted to get something cheaper but effective for my yeti. These for perfectly along the back wall, along with a couple of their smallest flexible ones they’re brilliant.
    Did some very unscientific experiments with my yeti, iceytek and different ice packs and these stayed cold much longer than my other packs. Work the order as nothing else similar in the UK

    False advertising.

    The Amazon product description (and displayed images) claim that this product is “made in USA”… but the Cooler Shock Ice Packs delivered to me clearly says “MADE IN CHINA” on the product.

    Amazon needs to update the description and photos and stop with the false claim that this is some USA product (and Cooler Shock needs to lower their price if these are now made in China because the price point doesn’t reflect that anymore).

    I bought these because I was getting ready to take some parfaits to an outside new student fair. It was forecasted to be 100+ the day of the event. The parfaits needed to stay cold all day and I was concerned that bags of ice would melt and get into the parfaits. When I went home at the end of the day, the coolers were still cool, some of the ice packs were still frozen and the parfaits were still solid. I did put two ice packs in each cooler but I’m sure that one would have worked – I was just being cautious. So glad I bought them. By the way, it ended up to be 105 that day.

    I live in Mexico and here we have sun all year round and hot weather.

    I have been using them for months in my fish bag when kayak fishing (obviously you just have to wash them well afterwards) and in the cooler for picnics on the beach.

    They are not as good as ice to spread the cold over fish, drinks, food containers, etc. But definitely they do help because the ice lasts much longer, so you require less ice each use; and that is where I see the savings that over time will pay for themselves.

    The reason for my rating is because regardless of the brand, the current price at the time of my purchase ($50US) is very high for what it is. I have fishermen friends who have not been able to buy them because adding their price plus having them arrive in Mexico makes them extremely expensive to spend on just an accessory for the cooler.

    If you see it on discount, do not hesitate to buy them…it is a good accessory to add to your cooler if you find it at a fair price for what it really is.

    I live in Florida, where it exceeds 90 degrees on a daily basis. And to add insult to injury, my van is black. I’ve been using an alpicool cooler for a few years now and up until recently, it kept my drinks cool enough on its own. But it’s been hotter than usual lately and the old fridge is having a hard time keeping up. So I bought these to supplement the workload and they bring the temps back down to where they should be with overworking the cooler.
    I purchased a 3 pl. and struggled a bit with loading the water with the crystals and found on the 3rd. One that by dumping the dry crystals into a separate container and adding pouring 5 cups of water in the empty case then adding the crystals, it was much easier to distribute the crystals evenly without them getting caked up in one spot and having to fight with it. Then I added the remaining 2 cups of water to top it off. Pic shows end of day after cooler shut off for 4 hours. Pack still has ice in it. Very satisfied. Worth the price as opposed to paying for cheaper models that couldn’t compare on this level.

    Made a 10 hour trip from Kentucky to the OBX . Bought 8 large Ice Packs to keep frozen foods cold and cold goods cool for 24 hours. I used 3 types of coolers:
    ** all coolers were hauled in my open trailer but tarped for a 10 hr trip. Ave ambient temp was 80-90 partial sun / rain.

    1- Medium size 5-day ice cooler ( used 2 packs for cold meats cheese ect) stayed cold 30 hours
    1- Large size 5-7 day ice cooler ( used 2 packs for frozen foods) stayed cold 60 hours
    1- XXXL Colman Older Cooler ( used 4 packs for cold bulk items fruits, veggies, milk, creamers, butter ect) 40 hours .

    the size, thinness & sturdiness
    stacks good in freezer
    like the B/I handles
    Can be used laying down to keep sandwiches, chips, cheeses, chips cool for 12 hours
    Used up right as drink divider like waters one side, teas on the other. Seems to keep drinks colder on edge for 24 hours.

    Does not keep items cold as Advertised to 48 hours. ( maybe never open the cooler once packed, but thats not realistic during a 48 hr period.

    Took the medium 5 day ice cooler daily to the beach loaded with beer & snacks with 2 packs every day. Only good for 6 hours.

    The thicker more brick looking ice packs last longer but bulky less storage.

    Result: thin is good for day trips on a boat , car trips or under an umbrella.

    Thicker other brands maybe better for direct sunlight hot summer days

    I needed an ice pack to keep my bait and my beverages cold when i intend to go fishing after my work ends which is usually 10 to 12 hours later in the day…After going through many reviews from various sources,i decided to purchase the hard pack and try it out.I was skeptical at first but Cooler Shock’s performance has been fantastic so far!! This is a product that will definately meet your requirements for a ice pack but also won’t hurt your wallet…

    We sell beef, pork, and chicken at a local farmers market but we were having an issue with keeping out meat frozen. Another vendor told us about these so we invested. Turns out that they are a great product but the cost is a bit much but it’s better than wasting our meat. The fill-up process is a pain but only have to do it once. Overall I would recommend if you need thing to last for several hours in the heat. They don’t really last over night from what we have seen, especially if you open and close a lot. Max hours I would trust to keep everything frozen solid would be around 12 hours with 10-20 openings of cooler per hour.

    Loaded up the cooler on a Tuesday morning for a 2 day trip in 90-99° days. Cooler was left in the back of our pickup (with topper) for both days and overnight. Brought the cooler in the house when we got home and didn’t get it unloaded until Wednesday night. Everything was still frozen!
    Read the other reviews to help fill easier as it can be tricky.
    I know it seems like a lot of money for over packs, but I promise, they are worth it.

    Decided to try these for a week long camping trip. Figured if I had to go down the mountain to buy ice then so be it. These packs did so well that our cooler stayed cold for the entire trip! I have a 90qt Igloo Max Cold which is supposed to keep stuff cold for 5 days anyway but the ice usually melts and it’s closer to 3 days. I used 5 of these packs (4 spread along the sides and 1 on top) and then used a small amount of ice to fill in the holes.

    Temperature was between 80-85 during the day and 60’s at night but the cooler was in a metal bear box which I’m sure was hotter than the outside temp. After 3 nights the ice I had put in was still frozen solid and the meat I had in the cooler (which was frozen to begin with) was still frozen. The packs did amazing and lasted us until the last day (5 days and 5 nights). The last day was probably as long as they could go as I could tell everything wasn’t as cold but they definitely worked like they were supposed to and I will be buying a few more for future trips.

    It’s so cold my beer became slushy. 2 ice packs was overkill for 6 beers, but still.
