Extra Large Ice Block Mold (Single) - Shape 5 lbs Bricks - Professional Silicone Mold for Crafting Giant Cubes, Ideal for Revitalizing Baths, Coolers and Bartender 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.

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.

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

Works great to form a block of ice.

Works perfectly

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.

Does take a while to freeze, but it's a lot of water. It doesn't slip out, need to maneuver a little. Easier than cutting a gallon water bottle to freeze

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.
