Berlinzo Premium Clear Ice Cube Maker Mold - 2 Large 2.1" Crystal Clear Ice Squares for Whiskey & Cocktails - Easy Release Ice Cube Mold - Storage Bag and Silicone Insert (Non-Electric)

I sort of kind of had my doubts based on experiences from other reviews left here. They were mixed. Some people had great success while others complained it sucked right out of the box. I followed the instructions exactly. Cleaned it well with soap and water first. Rinsed it well and then filled with warm water - not hot, not cold but warm. Froze it for over 24 hours and checked on it. It was so clear that I thought perhaps it hadn't frozen all the way through yet. I took it out and moved it around and didn't notice any air bubbles moving inside of the cube. I went ahead and removed the mold and then pushed the ice cubes out. They were solid and they were crystal clear. The eyes left inside of the bottom of the mold had not Frozen all the way through but even it was clear after the water drained out. This is a quality item and I'm very impressed with how my ice cubes turned out. My only wish is that it included additional silicone stamps for decorating the ice other than just the two that it came with. I highly recommend this and if there is a four-cube version, go for that one as well

This truly makes perfectly clear Ice Spheres! Works well, although, you do have to melt a good bit of ice in the bottom of the container before refilling it for another round of ice spheres. Still a very nice product and for the price, it works very well.

The ice comes out completely clear if you go through the process very slowly and used high quality water. I boil my water, allow it to cool completely and then filter it in a Brita jug. You have to leave the ice sitting in the mold for 5-10minutes before attempting to remove it too.

I’m giving this product 5 stars because I LOVE it. Just keep in mind that these ARE large cubes. They’re ideal for thinner-walled glasses with a wide base. As for your standard whisky tumblers, I’ve only got one it’ll fit (and I’ve got a lot of variety of tumblers in my pub). Still: Amazing clear ice. I bought all of their ice products after this order.
