Zoku Set of 2 Silicone Ice Sphere Molds, Stackable 2.5-Inch Ice Ball Maker, Keep Drinks Colder Longer with Less Dilution, Leak-free, Easy-Release, Red

(Note: I have posted pics of this product)The product, and the concept, are absolutely fantastic. Glad I purchased - and I wish I would have done so much sooner.I did lots and LOTS of research before I decided to purchase the Zoku brand. Of all the various designs, this one seemed to be the most straight forward and user friendly. And I was correct.Product makes perfectly spherical shaped ice (see my picture). The ice is very dense and melts VERY slowly. One evening of `continuous use' the ice ball lasted approximately 3 hours. This was indoors and being used around room temp - about 70 degrees. I suppose there could be different results if used outside on a hot summer day.The molds are wide - which prevents them from wobbling when opening / closing the freezer door (see picture I posted). They do not spill or leak water once filled. The water does expand upon freezing, which may cause slight overflow near the fill hole. Not a big deal, and generally unavoidable.After the ice is frozen (directions say to wait 8 hours) the ice pops out without any problems - no cracking, does not get stuck, etc. I make several batches of ice spheres and simply keep them stored inside a zip lock bag in the freezer. If the ice ball does not melt completely after I am done drinking for the evening, I simply leave it inside the glass and place the glass with the ice ball back in the freezer for use the next day.Lastly, be sure your cocktail glass is around 3.5 inches wide (see my photo) all the way up and down (i.e., not tapered). The space will be needed to accommodate the ice ball. Anything smaller and it definitely will not fit.EDIT / UPDATE (08/15/2014) - My comments above indicated that a glass of 3.5 inches would be optimal. However, I just noticed that my pic with the measuring tape is actually 3.25". Hence, I am updating my review to reflect that a glass of at least 3.25 inches wide is optimal (of course, larger will also work). I also updated the notes in the pic I posted to reflect this correction.

I have tried numerous silicon trays, balls and all manner of devices to make large ice for cocktails. These are the best I have encountered over several years of searching. They produce a smooth sphere of ice. Most importantly is that extracting the ice ball from the mold is very easy. I have 4 molds and it takes about 5 minutes to remove the ice from the 4 molds, refill them and return them to the freezer. This is not a “clear ice” device which is not important to me.

These large ice cube molds are perfect for elevating my icecube game! The molds create big, slow-melting ice cubes that keep drinks cold without diluting them too quickly. The silicone material is flexible, making it easy to pop out the ice cubes without any hassle. The large size is ideal for cocktails, allowing for a sophisticated presentation and ensuring that drinks stay chilled. I've also used them for iced coffee and flavored water with great results. These molds are durable, easy to clean, and a fantastic addition to any home bar. If you want to impress with your drinks, these large ice cube molds are a must-have!

I found it easy to fill and pop out the ice cube.

For the luxe mold with squares and wavy lines:There's no instructions but it's pretty self explanatory. The ice lasts a really long time and looks amazing. The size is nice and I like that they're stackable if you buy multiple. Feels sturdy enough to last awhileFor the deco mold with flowers:GET IT!!!! Best ice maker for the girlies ever omg. Cutest cocktails in the world with this ice

I am obsessed with this product. I purchased these last year for the first time and used them the entire summer. I basically kept making ice balls and popping them into a freezer container so that I'd have a constant supply. They're amazing!Basically, you get two silicon spheres, each of which separates into two pieces. There's a hole on the top in which to pour the water. I usually over-pour and then just flip the whole sphere over to drain the excess from the top cavity. The water inside the sphere will not come out if you flip it over, nor does it leak from the middle seam. For whatever reason, these freeze up quickly and you can make several in a day. I've looked at several other ice ball makers that were way more expensive than these, which were made of a hard plastic, and they aren't as fun or as easy to use because you have to run them under hot water to release the ice from the hard plastic sphere. These silicon spheres just push out from the flexible material. Very simple to use.I originally purchased the one set, then another. And then several more for gifts. And, my 11-year-old niece was obsessed with these so I bought one for her too.The balls will not fit into every glass, however, due to the size but these ice balls can also be used in punch bowls made out of punch ingredients and as ice for injuries. There's as much potential as the imagination can come up with. I'm wondering now if Jell-O balls can be made from these...Overall, the most fun and ingenious product I've gotten in quite a while. Every human needs a set of these!I love Zoku!

I researched about ice sphere systems, and everything pointed to these being superior. 4.5 stars. I have zero complaints. They create magnificent ice spheres. Of course they’re not clear, I wasn’t expecting that. When they’re filled to the proper level, they do make perfect ice spheres that are easily extracted out of the mold. I’m not sure what more you could ask?

Ease of use.

I had another brand that were very difficult to use and the rubber all disintegrated around the edge of the cap. I bought these and oh my goodness, these are outstanding! So easy to use, and so easy to get out of the container. The only thing I don't like is filling them because if I use my water dispenser in my fridge the water goes all over everywhere so I have to fill up a measuring cup of water and then fill each one up individually that way. But it is worth it, these are fantastic.

Wir sind hier große Fans der Zoku-Produkte, so auch von diesem Eisbereiter.Einmal mehr ist das Silikon komplett geschmacksneutral und lässt sich unkompliziert in der Spülmaschine reinigen. Die Form schließt auch sehr gut ab, so dass man keine Eiskrusten im Gefrierfach durch ausquellendes Wasser ansetzt. Und die fertigen Eisstücke sehen auch hier sehr cool aus. Sie machen sich super in Karaffen mit Wasser und Kräutern oder Scheiben von Zitrusfrüchten.

Fun but also practical. These moulds produce nice big, round ice balls. Working on the principle that a sphere has the least surface area for its volume of any shape, ice balls cool your drinks with the minimum dilution. The alternative of producing a cube or round section of ice and placing in a press is expensive, even with some more 'budget' devices on the market. Conversely, most moulds are quite small. So, while these might seem pricey, I haven't found a better value for money solution.A few reviewers (on amazon.com) have commented that the ice doesn't come out clear despite using pure water etc. Please refer to the excellent Craft Cocktails at Home by Kevin Liu to understand why and how to achieve this if it's really that important to you. I like the tip from another reviewer of putting them in bags whenever another is ready since they take quite a while to freeze and saves having to buy lots of moulds.Personally, I just love being able to cool my Old Fashioned with something effective and slightly funky.

Likes nothing than whiskey on a rock every evening. Jave 4 different sphere mould in the freezer but nothing works like this. Save a lot of stress on fingers too, the best I've used.

Le mode d'emploi et le précise pas mais il vaut mieux ne pas remplir totalement l'espace.En revanche les sphères se brisent parfois en deux sans raison apparente dans le congélateur (??)
