Everlasting Ice RX Reusable Ice Packs for Cooler (4 Pack) Up to 48 Hours Freezer Packs for Coolers and Lunch Boxes Cooler Ice Packs for Lunch Box, Camping, Fishing, Beach, Road Trips

I am incredibly impressed with these Everlasting Ice RX reusable ice packs. Living here in Louisiana, the heat is absolutely brutal, and these packs are exactly what we needed! I use them practically every single day in my insulated ice bag, and they stay freezing cold for hours at a time. They are perfect for grocery shopping because I never have to worry about my perishable food getting warm or spoiling on the drive home. They are heavy-duty, durable, and clearly built to last a very long time without leaking. If you need a reliable ice pack that can actually survive intense heat and keep your things cold, I highly recommend these!

Stays cold for a few days! Took camping in Colorado so wasn’t direct heat but they managed to stay cool for over what is mentioned ! Great if you don’t like refilling with ice

Ice packs worked great for keeping my lunch’s cool even in extreme heat. Definitely works better then a standard ice pack

I wanted to just take a back pack but not use ice for a hot beach day. These were perfect and they actually did last so I will purchase them again.

I've been pleased with these ice packs. I tend to use them on 14-15 hour days, and they are usually still pretty cold, if not still frozen, by the end of my day. You receive these packs flat, with instructions to pour in a specific amount of water. The water interacts with a product inside, which quickly turns into a freezable gel. It's easy enough to do. One of the packs broke in my lunch pack. This surprised me, as there was nothing in my bag that could have punctured or torn it, and I filled the bag with exactly the amount of water in the instructions. I haven't had that problem with the other two of this size that I've used so far, not with two others of a different size. In any event, I've used these for a few months, and am satisfied.

It is extremely thick and large… HOWEVER, it did indeed last very long. I used it to keep my breast milk cold for 5/6hr flight and a long travel day. And it stayed frozen with only two packs in the small cooler bag I had. The ice pack is basically just plastic and no leakage if you follow the directions on how to fill it properly. Overall GREAT ice packs for the price.

Great for size and they stay cold a really long time. We live in the HOTTEST state Arizona so these are great

Purchased these to use in place of dry ice as I needed to keep some food items frozen for my dog on a 2 day trip. Since this literally states “Replaces dry ice” I figured it would be perfect. I prepared the items as directed and after 24 hours put all 4 of them in a small cooler along with the frozen food items. I only drove for 5 hours the first day so was beyond surprised to discover every item in the cooler had melted and turned to liquid. Which then leaked all over the cooler and obviously ruined the items and made them inedible. I ended up having to find a store nearby to run to to purchase additional food for my dog (not the same as the original food was from a specialty store) which she wouldn’t eat. So a lot of wasted money and in fact - I ended up LOSING money by purchasing this product and believing the BS claim that it actually replaced dry ice. Don’t waste your money. Using a bunch of ice would work just as well if not better. Absolute joke.

It works great good product

Lasts a long time. Good product
