Tundra Series, Long Lasting Reusable Ice Pack, Purple

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

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.

I have the 5lb, 2.5lb and the .75lb. They aren’t cheap price wise but they freeze down colder than anything else I have ever tried. Using them in my Yeti cooler and prechilling with dry ice they lasted for 5 days and I had to break the ice off of the Arctic Ice at the end of the weekend. The side with the Artic ice was still frozen but my other side of the cooler had melted. When using the .75lb in our soft sided Yeti we have to put cardboard between the packs and some goods to keep them from freezing. Picture is of ice on day 3. This is more ice retention than when I used dry ice (solid co2) to super chill my cooler full of ice. Some reviews are complaining of poor results. When I use the artic ice in a cooler bag they don’t work as well as when in full contact with ice for long duration. So poor results are due to poor execution not due to poor performance of the ice pack.

The delivery did come 2 days before my camping trip, which I nvr expect it to reach early. Though it said will be arrive on 3 Sep. Anyway the product is fine, lasted 48 hours.
