Berlinzo Premium Clear Ice Ball Maker Mold - Large 2.4-Inch Crystal Balls for Whiskey, Cocktails, and Bourbon - Easy-to-Remove Sphere Mold (Storage Bag Not Included)

Perfect ice clear balls with just 1 try! Easy to use. Froze for 48hrs and left to thaw for 8-10mins. No difficulty pulling out, just had to alternate left and right a few pulls to eventually slide the molds out all together.

Pricey, but it does the trick. I’ve got the single mold. Ice comes out relatively clear and very solid. The shape is great too. Almost perfectly round. Doesn’t leave a plastic/rubber odor like some other products. It also doesn’t leak or create a crazy mess like other products. My ice spheres still aren’t perfectly clear, but I think that just comes with practice and experimentation. Otherwise, this product’s worth a try for sure. To my fellow whiskey sippers; Enjoy!

Why so many negative reviews?! All the talks about removing the ice from mold being difficult is totally not true. Easiest thing to do in the world.

tl;dr: This unit makes excellent clear ice with low effort. It helps to know the science behind it to avoid pitfalls. It's worth the slightly higher price for the build quality. I couldn't be happier with the huge clear ice cubes it makes for my whiskey drinks. Basic science behind clear ice: As ice crystals form, contaminates are pushed away. Normal ice trays freeze from all directions so contaminates end up in the middle of the cube, making them cloudy. By surrounding the mold on 5 sides with insulation, the water directionally freezes (top-down in this case) leaving a cube of ice that has pushed all contaminates into the water below the mold. Stopping the freezing process before the reservoir of water freezes aids in mold removal. Fit and finish: I chose this model because it has a hard outer shell with dense insulation molded to an exact fit. Other models use that cheap layered white foam with no shell. Inside of the molded insulation is fitted the reservoir, which again is a high quality plastic and fits perfectly inside the insulation shell. Finally, the molds are a thick silicone that has a high-quality feel. 10 out of 10 for fit and finish. Functionality: Each cube has FOUR holes to push contaminates through verses only 1 in other models I looked at. It is easy to fill, easy to insert the molds, and just a pleasure to use. You will need freezer space for it, making clear ice takes space. Removing the molds can be frustrating. Be patient, follow instructions and let the thing sit for 10-15 minutes prior to attempting removal. Alternate sides, go slow and they eventually break free. It is easier if the freezing process is halted before the reservoir has frozen, but this takes trial and error to dial in. My freezer's optimum time ended up being 27 hours. After use, I found that I was able to simply pour the reservoir water out, then pull the thin bit of ice that did form straight out and restart the process immediately. Leave it too long in the freezer and you'll have blocks of ice to deal with. Tips: Fill the reservoir with WARM water up to the point the bottom of the molds will sit. Then insert the molds and fill with COLD water. After filling, tip slightly from side to side to allow any trapped air to escape. This will aid in the preventing reservoir from freezing too easily. Ice heaves happen. Sometimes as ice forms/expands, it pushes up. So some cubes may be larger than others. It's still clear and cool.

Excelente producto, tarda en hacerse el hielo pero si sale completamente transparente
