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!

This works very well. The ice is super clear and the extra stencils for marking initials on it were also a big hit. Note: it is a little difficult to get the ice out of the mold if you leave it in for more than 24 hours.

This little unit only freezes four cubes at a time, but does a pretty good job making relatively clear cubes.A few of my glasses are just slightly too small for these cubes, so I don’t quite fill up the device all the way in order to allow the cube to be smaller to settle in the bottom of the glass

The media could not be loaded.

I’ve tried another brand : NO LUCK!These worked great.. only issue pain in the tooooosh to get cubes out .. but worth the fight!😉

The ice cubes this product makes are awesome. So clear, it really takes the presentation of your cocktail up a notch. It can be a little tricky getting the cubes out of the mold, but it's totally worth it!

IDK what some of these people are talking about. I used unfiltered tap water, had no issues. They're not hard to take out, either. Mold has slid come out pretty easily. No need for hot water or anything. Clear spheres with some clear ice and a giant air bubble below the molds. All I did was follow the instructions and I've had perfect runs so far (on my 3rd batch). Very happy with it. Storage bag only holds 6 spheres, but that's a nitpicky thing to ding it on. You could probably just use a ziploc (or maybe double them) to store more spheres. I'll find out when my next batch is done, I guess. Excellent results, very happy with my purchase.

First time using it made perfect ice, corners had some frost that went away after a few mins and left perfect ice. Expected imperfections but it was actually perfect once it melted a little. Size is good even for a regular top freezer. Would never buy at normal price of 60 but discounted prices of 30 and 40 a little more reasonable. Wish it had spheres instead of cubes for even longer lasting ice and easier for all glasses but the cubes are straight edged cubes so can't complain. Great product, feels solid. Hope it lasts.

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!

Besonders das Lösen der Eiswürfel ist immer noch schwierig und ich habe immer wieder Lufteinschlüsse. Da ich aber mittlerweile vermute, dass das an mir liegt und nicht am Artikel gebe ich dafür keinen Stern Abzug.

Très bien. Les glaçons sont bien transparents.
