KARP Clear Ice Ball Maker Crystal Clear Ice Sphere Maker Prepare 2 Large Round Ice Balls, Clear Ice Cube Maker for Cocktail, Whiskey & Bourbon Drinks, Gifts for Men (Ice Ball Size 4 cm)

A wonderful thing!ProsBig, spherical, clear ice as desiredCons1.Occupies substantial space in the freezer. Just fits in mine… lucky me!!2. Min 24-48 hrs are required for one lot3. Extraction of ice requires a fair degree of effortPrognosis- the end state is worth the effort and due to the science involved, this is probably the easiest way to get clear ice.It is recommended to prepare in advance for the parties. The ice made can be stored in other containers in the freezer.

It takes about 16 hours to get the spheres ready. I’ve experimented with normal RO filtered water as well as with RO water boiled and cooled to room temperature. Needless to say, the latter comes out clearer.You have to pack the mold snugly else the hemispheres will be slightly offset and you’ll see a seem.Overall: Good stuff - nice indulgence for a drink.

You might see many other Ice Sphere cups being sold which are smaller. While I haven't tried them, I can say with certainty that they will at best make cloudy spheres, and at worst, no spheres at all.This ice box works on the principle of unidirectional (top-down) cooling. That is why there is the thermal insulator in the form of the external box. Additionally, the caste for the spheres is a perfect mold. Easy to remove once frozen and crystal clear. Check out some videos online to see why this method works.I simply enjoy making these sphere.A special note, due to the nature of the ice that i created, these spheres of ice not only retain their shape, but also take about 2 hours to melt. Thus it keeps your drink cold and doesn't dilute it. Think whiskeys, then this is the perfect ice!

My husband went crazy for this. You have to give it time it mentions (24 hours) but it yields the results. The ice balls are beautiful and clear. I infact got beautiful ice cubes at the bottom of the box. The size is good, and it is easy to use. It is easy to clean too but take care of the insulation since it is basically thermocol. No leakage observed.

Had bought cheaper ones few years back which didn't produce spheres let alone clear ice.This is value for money and does what it says.Had to tinker with the freezer settings till the ice became perfectly clear the first few tries. My firdge was set to 7.5-8 to give perfect ice. Kept for 26-30Hrs. I experimented with water and found that boiled water which was cooled to room temperature gave clear ice compared to direct tap water. Another benefit is the ice cube formed in the bottom of the container can be used too and are clear too. This cube which can be broken into 3 pieces can be use while making cocktail too in the shaker.Can make many clear ice spheres and keep for a small party which I found was an advantage to the "ice press" which you had to wait for it to cool down to make another ice sphere and u had to keep more amount of ice in the freeze to use the "icepress" when making for same amount of people. U can get a different model with more spheres to increase the amount but this is satisfactory for now.
