Alaskey® Extra Large Ice Block Mold with Lid (Single) - Shape 2.5 lbs Ice Bricks - Professional Silicone Mold for Crafting Giant Ice Cubes, Ideal for Revitalizing Ice Baths, and Coolers Accessories

Works great. Bought two with lids. have a large Yeti cooler. Keeps me from buying blocks as long as I keep building and rotating! Easy to use and convenient. Pay for themselves quickly. I recommend them.

Solid sturdy material to make the giant ice cubes! 5 lbs is a big piece of ice!

Love it, every two days I make new blocks. I have four of them.. I stack them in my freezer for the beach, etc. ready for parties. Lot easier than wasting your money on bag ice from the ace machines. Highly recommend.

Good size, Hard to get ice block out, we use the to help keep our animal troughs cool in the summer

These are good quality. All of these at this size are way too expensive for what they are. But if you are dead set on getting ice blocks of this size, then these are the best price and quality.

These work great

Very well made and durable. I have used this to fill several ice blocks and even with the ice "bulging" during the freezing process, no damage to the containers. Lids fit securely enough to water from spilling when carrying from sink to freezer. Getting ice out is very easy if you rinse briefly with some water.My only recommendation would be to add a visual "FILL LINE" as a reference when filling with water since filling to the brim can result in spills or lid popping off during freezing.I originally got these to mass-freeze ice blocks for a cold plunge tub, so the size of the ice blocks has been great.

Good quality. Nice and thick rubber. It's very hydrophobic so it dries quickly. I was able to pull out a block easily as well. There is some give/flexibility to the rubber. So when the ice froze, one wall bulged out a little bit. If you want a perfect block maybe go with something a bit more rigid. For me it's not a big deal though. I did fill the containers completely full though. Next time I'll leave some space for expansion. The lids are worth it as well. You can stack the containers on top of each other in the freezer.
