Arctic ICE Tundra Series, Long Lasting Reusable Ice Pack

After more than 10 days in the freezer at -16 degrees celsius the cooling elements are still not fully frozen Are these faulty??

I bought three of these for a Lifetime 77 quart cooler (which is an insanely great cooler - way better than a Yeti!), hoping they would keep our food cold for at least 4 or 5 days of our 10 day camping trip. Well, they lasted 9 days before I had to buy ice!! I actually should have only used 2 of these in the cooler, though, because these are incredible! However, it's critically important to properly prepare your food and cooler -- pre-chill or freeze food & drinks ahead of time and pre-chill your cooler for at least a day or two (just throw a couple of bags of ice in your empty cooler). You need to properly pack your cooler, too - Youtube has videos on this. I put some frozen meat on the bottom and it stayed frozen right up until I had to put in ice. This sounds weird, but it was almost inconvenient because I had to remember to take out meat to thaw! I jammed in a container of sour cream nearer to the bottom, right next to one of the ice packs and it froze solid!! I had lunch meat that also froze solid - and it was on the top! Definitely should have just used 2 ice packs and put the third in my drink cooler. The key with these ice packs is to FOLLOW THE INSTRUCTIONS. They need to be put in a freezer that is at -5 degrees, which most kitchen fridge freezers can't get to or can't stay at consistently. These need to go into a deep freezer or they just won't freeze solid. And, these things don't freeze overnight - they need 2-3 days at least (I put them in for a week!). Definitely buying at least one more for me and will be buying these as Christmas gift for my kids that camp!

My second order. Very effective in keeping items cold for a much longer period of time !

These Arctic Tundra Series freezer packs have been fantastic. They kept my frozen food frozen during a cross-country road trip using only a mid-priced cooler ($65–$75), which really impressed me. I also used one on a trail ride, and when we stopped for lunch, the water bottles—started at room temperature—had actually begun to freeze. That says a lot about how cold and consistent these packs stay. They’re made from high-quality plastic that’s durable and easy to clean when not frozen. The integrated handle is a great touch and makes them easy to move and position in a cooler. One tip: if you store these at room temperature, be sure to put them in the freezer a few days in advance and set your freezer colder than usual. These packs are dense and take some time to fully freeze—but once they do, they perform extremely well. They’ve worked perfectly for my needs. I currently own three XL (5 lb) packs and four L (2.5 lb) packs and will continue to buy more as needed. It’s really nice not having to stop for ice every day. Highly recommend.

Dice "Pack" y solo viene UNO. No lo hubiera comprado de haber sabido que solo es UNO.
