W&P Prism Single Ice Mold, Perfect Etched Large Cube, Slow Melting for Whiskey and Cocktails, Food Grade Premium Silicone, Dishwasher Safe, BPA Free

Beautifully designed to seal in cube.

Just what I've been looking for! You might say I've been on a mission. These are my 4th effort to find the right forms for big ice cubes to use in fancy cocktails. The first one I bought had a funky smell, no matter what I did to try to get rid of that. The second ones were great, just too small for my intended use. The third ones were awful--hard to use, forms would not come off easily, the cubes would come out cracked. I posted reviews for the latter two. These are the perfect big size, have no odor, come with helpful lid, and the cubes are easily pushed out of the forms. Success!

I absolutely love these trays. Four pieces of ice and you have enough ice for 4 people! Push the ice up from the bottom and it comes out so easily. Love this (I do find the lid pretty useless).

I love it , the cubes last a long time in my Coool tumbler but it’s hard getting them out of the trays. And I wish it was at least a 6-8 pc tray

Finally! This mold actually makes clear ice. Anything that doesn't talk about directional freezing is fake. This is the real deal, and it freezes in half a day!

This thing works excellently, but fair warning, these cubes are huge. Bigger than my rocks glasses that I intended to use them in. I put my adult beverage in and then grabbed the ice tray and only then realized the error of my ways. I took a pic of a single cube in the glass for comic relief; it was clear of the beverage by a good half inch.But other than that, amazing cube tray, works well. Allows you to simply push one cube out at a time. The cover is a bit of wasted effort in my opinion, but I guess nice if your freezer is nasty or something. No clue why you’d ever need to use it really. But great ice tray.

It'll take a bit to perfect the outcome, however it's super fun and I'm enjoying experimenting with it. I like the fact that it's fairly easy to get near to clear ice cubes with this mold. In research on this, there's apparently a method to extract the air that makes ice cubes "cloudy", vs. clear. This mold helps with that situation even with tap water. I've been more successful with crystal clear cubes after letting water sit for about 12 hours and then gently filling the mold. I have a tendency to overfill the mold and get a bit of an irregular shape.It seems like commercial ice machines have the ability to extract air to make crystal clear ice cubes. I don't want to go that far, however I'll experiment with distilled water, etc. to see what the effect is with that. I just don't want an odd taste due to the water used to make this massive ice cube. Who knows, however I'll keep experimenting with this super cool product.I'll keep trying. I highly recommend this product. It is very easy to use, it is high quality and will likely work well for a long time (durable). I can definitely say that the ice cube that is produced lasts for a very long time in the hot summer heat. Massive.Very fun!

This thing makes great, huge cubes! What I love about this brand is the lid and more specifically the color of the mold. I used to have all black ones and after the first use, they discolored and looked like there was a film on them. I knew they were clean, but didn’t look it. I really like this one!
