Very good , long lasting freezing

works well for the price and convince of next day delivery. held temp well. size was decent, could have been larger due to the size of my colemans coolbox easy to use and sturdy

Good value

I bought these freezer blocks specifically to help cool down my fish tanks during the recent heatwaves, and they’ve been an absolute lifesaver. Once frozen, they stay cold for a good amount of time. I pop them into ziplock bags and float them in the tanks (never directly in the water) whenever the temperature starts creeping up. They bring the temperature down gradually and safely, without stressing the fish. They’re reusable, don’t leak or sweat much, and freeze quickly—perfect for rotating throughout the day if needed. I also appreciate that they’re compact enough to fit around the tank without being bulky. If you’re an aquarium keeper worried about rising temps in the summer, these are a super handy, low-tech solution. Highly recommend!

Great to have when you’re going out somewhere and you’ve got cold drinks and sandwiches when you arrive at your destination

They worked very well for my insulin on the way to my holidays during air travel .
