SIMPLETASTECrystal Clear Ice Ball Maker Mold - 2.36 Inch Clear Sphere, Plus 2 Ice Ball Storage Bags, BPA-free Silicone Large Sphere Ice Mold, Ice Cube Tray for Whiskey, Cocktail and Drinks…

Love it. Works as claimed. I have boiled the water to 122f, but my well water is pure and I get clear spheres either way.

This works well. It’s a slow process, but easy enough to get totally clear ice - need to use boiling or very hot water that’s also been filtered to get totally clear ice. Can make 2 clear balls a day - so plan in advance if you’re having a party!

J ai bien apprécié la taille des glaçons car il tiennent longtemps pas besoin d en remettre souvent . Il faut un peu de place dans le congélateur mais ça n est pas très grave .

Short version: Used filtered water (Britta, not boiled, not distilled), stuck in freezer, got round, clear ice.Long version:I was skeptical how clear they would be. It was to my understanding the best way to make clear ice is to insulate the top so that it freezes from the bottom up squeezing the gasses out. This mold appears to leave the top more exposed so I was skeptical if the ice would actually be clear.My wife pulled the mold this morning and sent me a picture, I was kind of underwhelmed, it didn't look all that clear. Turned out it was just some frost on the outside, once the cubes are wet, they really are clear.There were some lines in the ice at the edge of the mold (where the holes are) but these cubes look great.The only real negative to this mold is that once the unit is filled, the water is VERY close to the top and it's easy to spill it (not sure why the outer container isn't even 1/2" higher) but it doesn't matter, it makes clear, round ice and it's cheap.Edit: Added a picture of my balls. So far we've made three batches:The first one was absolutely perfect, wife doesn't remember exactly what she didThe second one the balls had crazy imperfections at the bottom, you could see where the freezing ice was forcing the gas out of the water. Really interestingly; when I rinsed the ball with cold water to see how clear it was, the ice at the bottom immediately crackled and cracked. Wifey still doesn't remember what she did for water (was it from the Brita, was it fresh through the Britta, was it in the fridge.Third batch; after the disappointing second batch, I figured it was time for some scientific method. I used already chilled water from the britta that had been sitting/settling at least 24 hours. I soaked the molds in warm water (the idea is to make ice slowly, didn't want the cold mold to give it a head start). See the photo, these balls came out clear without only some minor lines at the bottom (again it looks like the gas is getting squeezed out the bottom and causing lines in the ice.Bonus interesting: after removing the mold there's a bunch of ice at the bottom of the ice maker, when you fill the container with hot water, you can see the bubbles escaping from the ice as it melts.

I bought this on a whim not expecting super clear ice, but it turned out great on the first try. I used water from my Brita and got crystal clear ice.I haven't tried other types of water but it says you can use filtered, boiled & cooled, bottled or distilled. I was surprised how easy it was to pull the silicone mould out as it looked like it wasn't going to come out easily. Then I just had to knock off the ice on the outside of the mould which only took a whack against the sink. The white butter shell doesn't take up too much freezer space.
