Sphere Clear Ice Cube Tray - Silicone Ice Ball Maker Mold，Crystal Clear Round Ice for Whiskey and Cocktail

Just put it in the freezer, but very dissapointed with the quality. A thin plastic tub, some insulation around it, and two silicone moulds. I'd have with a tenner myself. That said, no idea if it works yet, I'll update in 36hrs. If it doesn't work, it's going back because it certainly isn't worth the materials.

It does take several trials to ascertain how long to leave the device in your freezer, of course, but on the third trial, we had a tray-full of crystal-clear ice balls for our cocktails. They really are lovely and very entertaining. Don't forget to show admirers that they're tiny ice lenses and project a real image (a kind of image) of a light source. Cool cocktails and entrainment for cheap: what's not to like?

Grabed an open box one cheap, it works as well as the pricier ones, does not look great so maybe not the best gift but it does the job. Nice smaller balls that can fit in a collans glass.

Buen producto. al momento de retirar el molde hay un poco de problema

This does make small, clear ice spheres that look great in drinks. However, the outer closed cell foam body appears unfinished and is comprised of layers of foam that are glued together unevenly. It needs an outer plastic body to give it more rigidity and to give it a finished look. Looks cheap. The excessive flexibility of the unit over its length makes it more challenging to transfer this into the freezer without spilling water once it is filled. The individual molds are of silicone rubber but the space between molds is open air rather than solid silicone, like some other molds. This space tends to get filled with overflow water and creates a layer of ice that makes extraction of the top half of the mold more difficult.

At first glance this appears to be a cheap knock-off type purchase; it's as if someone was making it their garage or basement. However, the lack of a flashy or gloss finish doesn't make this any less effective than other similar items. The technology is the same: directional freezing.It took a try or two until I had this working. You don't have to use hot water, warm water does help because it aids in the directional freezing.Note: if you have one, put the whole thing in a plastic container because it drips or overflows.I fill the base about 2/3 full then put in the bottom gasket. I add a little more water, maybe 1/2 way up the gasket, before adding the top gasket. I press on the markings in the middle and around the side to fasten the two before pouring water into the holes in the top of the spheres.I use a turkey baster to suction out water that pools in the top.Also, I find something in the freezer to put on top to hold it down because the gaskets do float.Don't let your curiosity get the best of you: if you peek before it's fully frozen, the ice won't be clear. The gaskets are tougher than they appear. This doesn't mean tear them off; however, you can pull a bit to release the spheres. It might help to set it out for a bit, or work a corner loose and pour some warm water under the lower gasket.Enjoy.
