I used the ice sheets in multiple coolers, empty, with food and drinks, and with loose ice. These sheets did not last more than a few hours. I tested with the coolers outside (it was cold one day), inside (high 60s) and outside (70s) with the same outcome that they did not last more than a few hours. I would not recommend these sheets. I did contact the seller and they offered to replace (sounds like this is not how they were supposed to perform) but atlas they never sent any. I WOULD NOT RECOMMEND. ### ⭐⭐⭐⭐⭐ They stay frozen for DAYS!!!!!! *by S***H on Reviewed in the United States on October 15, 2018* Love Love Love these!!!!! I drove from Maryland to Florida over 3 days and these actually stayed frozen the entire time!!!!! I thought I’d need to bring them in the hotel each night to refreeze but NOPE they were just as solid upon arrival in Florida as they were when I put them in the cooler in Maryland. I HIGHLY RECOMMEND these!!!! ### ⭐⭐⭐⭐⭐ Thicker Better *by G***Z on Reviewed in the United States on August 18, 2021* Love them . I vacum bag them so they don't leak that slimmy stuff. Set 4 around your frozen foods in your insulated bag and your stuff will stay frozen for at least 8 hours. Heavy with 4 so I just use 2 for the short trips of 2 hours to the grocery store. I'll never use ice or those cold packs. Dip in water squeeze and freeze.Voila!! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/44629030-herolily-reusable-hdr-heat-and-ice-sheets-packs-extreme-freeze](https://www.desertcart.hr/products/44629030-herolily-reusable-hdr-heat-and-ice-sheets-packs-extreme-freeze) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-08*
