True CubesCrystal Clear Ice Sphere Ball Maker with Storage Bag - 4 Large Clear Ice Sphere Balls for Cocktails, Drinks & Whiskey - BPA-Free Silicone Sphere Ice Sphere Balls Mold

Great idea, but having 4 cubes above another 4 is not working.First of all the bottom ones never get really clear and secondly it's very hard to get them out.My suggestion would be to create a 4 cube only tray.The top 4 cubes come crystal clear.

imprescindible para almacenar los hielos transparentes y evitar que tomen olores del congelador y que no se peguen... al principio pensé que era un gadget mas... si lo recomiendo vale la pena

El proceso no es complicado, te permite hacer 4 hielos realmente cristalinos que hacen lucir mejor los cócteles que preparé. La parte congelada que se genera abajo del molde puedes aprovecharla para shakear, los superiores para la presentación. Efectivamente el proceso toma aproximadamente 18 horas para que se hagan bien los 4 hielos superiores, valió la pena esta compra!

UPDATE after one year:I'd buy this again in a heartbeat. If you care about cocktails, glassware and serving the best possible drinks to your friends and family, get this. In my earlier review I mentioned bottled or filtered water; update - totally unnecessary. Tap water is perfectly fine. Our freezer is set to 5F degrees. I don't think there's anything magical about the water or its temperature.Assemble the mold, fill it to within a quarter or eighth of an inch of the top, carefully place it in your freezer, then leave it alone for 16 hours. Take it out, LET IT SIT ON THE COUNTER FOR A COUPLE OF MINUTES, then grasp the silicone molds with your thumbs and index fingers and use your other 6 fingers to push downward on the rigid insulated portion; it should come off fairly easily.Then separate the lower silicone mold from the upper mold. You don't have to be gentle here: the molds are durable. If your freezing period was correct, the lower mold should be a mixture of ice and water.I remove the ice from the bottom of the cube mold by tapping it with a wooden spoon (over the sink). Once it's all off, put the upper mold face down on the counter, and push down on it... the cubes should loosen and come out of the mold. Immediately put them in the freezer. There's a storage unit available. If my storage unit is full, I just leave the new cubes in the upper mold.We recently purchased some Art Deco old fashioned glasses from Amazon and they're beautiful, but a bit too small for these cubes. So I take a (sharp) serrated knife and carve them into rough looking roundish cubes that look more interesting than the plain cubes. See 2nd pic above.TL/DR: Buy this if you care about cocktailsI’ve been using this for a week and a half, and it works really well. With the freezer set at 4°, it takes between 14 and 16 hours to make four beautiful, clear ice cubes. And guests really notice!Update: for best results, use filtered or bottled water. Fill to the fill line, let it sit for a while, then tap the housing to release any air bubbles lurking inside. With the freezer set at 5°, it takes about 16 hours to get fully formed cubes in the top mold and the proper icy/slushy mixture in the lower section. Do NOT use warm water to remove that icy mix from the underside of the top mold: you’ll damage the cubes and they’ll end up lopsided. I usually tap the partly formed “cubes” from the lower mold (which adhere to the top mold) with a wooden spoon to dislodge the extra ice. Then you can pop out your beautiful clear cubes. After sitting in the freezer a while (I put them in larger silicone molds I no longer use), I store them in a large ziplock bag. Still happy, still 5 stars.2nd update: the only issue I’ve had is an occasional bubble or two in the cubes. This is what I’ve landed on as my approach:1. Put the lower silicone mold in the insulated housing2. Fill the lower mold with bottled or filtered water3. Insert the upper mold into the lower mold4. Fill upper mold to fill line5. Carefully place in freezer set to ~5°F6. DO NOT TOUCH, MOVE, JOSTLE THE MOLD for at least 14 hours7. Remove from freezer after ~16 hours have passed, remove cubes8. Cheers!

Here's a photo of my first attempt - basically perfect!They say to experiment with 18 - 22 hours freezing. This one was frozen for 18 hours and was a little wet at the bottom (so not a perfect cube) but CRYSTAL clear. My second attempt I tried for 19 hours and THEY ARE PERFECT - square and clear.Your freezer might do the timing a little different but this is SUPER EASY. If you get the timing right they are easy to remove.I'm on a well with hard water... but I've a feeling this box is MUCH easier than a ton of others I read about where it's all how you hold your tongue, do this or that, use this water etc. I wanted easy, square and clear and couldn't be happier!

So happy that I’ve finally got clear ice in my gin and tonic. Sad I know. But it’s true!
