Sphere Ice Molds - 6 Pack - Silicone Ice Ball Molds with Built-in Funnel - Round Ice Cube Molds - Make 2.5 Inch Big Ice Sphere for Whiskey & Cocktails,Food Grade and BPA Free, Black

Originally I was skeptical that these would just make a mess in my freezer but I was pleasantly surprised. The seal held very well. They were easy to use and take out of the mold. Kept the ice in the right shape. Size is perfect for the standard glass. Very durable. It has practical use and effectively serves its intended purpose.

Love them but a little hard to get the frozen ball out of the mold.

Do what I need them to do, freeze ice into a single mass. Can be a bit finicky to fill, slow, thin stream of water or the neck "clogs". Sometimes they leak, but its only water.

Best purchase ever, this is no regular ice cube long lasting, easy to used and easy to clean, freeze in hours tops .

It will work for now, but I'm not a fan. The top and bottom don't fit together as well as they could. So far, I have made eight balls. Two leaked out in the freezer because the bottom fell off. There is a "seam" in the ball, so far two have split in half when I took it out of the mold. So far one has stayed to gether during the drink. Three are still in the freezer, so we will see.

These are so nice! My mother took them from me. I ended up buying another set and my best friend begged for them!!! Very classy looking!

Works fine. A little difficult to fill but nothing to worry about.

Ice BallsThe reviews appear bipolar. Some love them, some hate them. Not many in the middle.The haters say they leak, they’re hard to open or the lids fall off causing a big mess in the freezer (Blowout)On the issue of blowout:1. Dry silicone can be non-skid. Sticky is bad for assembly. A quick rinse before assembly solves the problem.2. Each half has three reinforcement ribs. Line the ribs up with each other to reinforce the entire circumference. Out of line ribs create an uneven torque on the shell creating gaps which WILL leak.3. Allow "head space" when filling. Each shell holds 4 oz. Start with 3 oz. and experiment from there.4. Water expands when freezing. The head space allows for initial expansion without blowing the halves apart until after the seam is frozen over and sealed.5. Place in a shallow freezer proof pan just in case. That way you can avoid iceberg formation (a Titanic mistake) inside your freezer if things don’t go right.On the issue of hard to open:1. Depending on your freezer temperature, 10 to 15 minutes in the refrigerator will warm the shell enough to soften the silicone without melting the ice.2. Roll the shell between your palms as if you’re peeling garlic. This will wiggle the shell loose from the ball.3. Once undone, grab your balls, stuff them in a Ziplock and toss them back in the freezer.Please remember to wash your hands before touching your balls. Some bacteria (including Salmonella) can easily survive freezing. The horror stories of improperly maintained hotel / restaurant ice machines are all the proof you need 🤮
