Techni-ICE HDR Sheets,(1 Sheet) Better than Ice or Gel Packs! Reusable, Dry Ice Replacement

I love these sheets. I bring my cooler with me wherever I go. Using the Techi-ICE Sheets I know that my food stays cold all day.

I really wasn't sure this product would work as advertised ,but I was very happy it did. The way you need to activate them seemed odd ,but not difficult.
Food and beverages stored in my cooler after 16 hrs.at high tempertures felt as though they were just removed from the refridgerator.
I use 2 1/2 sheets in a twelve pack cooler. I have yet to have any problem with any kind of water leakage as they thawed ( one woman stated she had). Considering the great cooling you get if I ever did get any water leakage I would just stick the sheets in a ziplock bag . Heck , you would do that with ice.
I also was very satisfied with the extra room I have using the sheets compared to ice.

I have had the same Techni Ice packs for 7 years! Still work as great as they did on day 1. I am looking for more. I was worried they didn't make them anymore because it had been so long. Glad to find them again.

I came back to change my review. At first I loved this product. I used it in a drink bag to carry drinks They stayed cold more than any other ice pack I have used. And the fact that they come without water was great for storage. But it is also their biggest downfall. It tells you that water goes in through a one way system but it comes back out also if you are so unlucky to let them thaw. I learned this recently the hard way. Amazon woul not let me edit the stars but I would have changed tham to 2 stars.

I recently purchased ten sheets of Techni Ice and was surprised how easy it was to use. Three hours in my freezer and it was frozen solid. Techni Ice is a definite buy for anyone tired of spending bundles on ice for camping, fishing, or whatever. Cheaper than dry ice and last longer than regular ice. Plus, I can use it again next camping trip. I definitely got my money's worth.
