ZOKU Set of 2 Silicone Ice Molds, Shark - Large Shark Ice Cube Molds for Craft Cocktails, Keep Drinks Colder Longer with Less Dilution, Easy-Release, BPA-Free

(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.

The Best... These two round ice cubes are perfect. 1... They take up very little freezer space 2... They contain all the water with no leakage in the freezer. 3... They release the iceball easily. 4... The iceball goes in a Ziplock bag and the refill is easy. 5... The iceball is the right size and melts very slowly in the glass If I had to name a bad thing about them... well, that would be like trying to point out the bad part of good sex. I guess I'll think on it and get back to you. I really like them. Two ballmakers is enough for my Wife and I but if I needed more, I'd get more of the same.

I rarely give product reviews, but this product deserves a five star review. It is the best round ice cube maker I have found, very easy to use and consistently makes perfect spheres. It doesn’t make clear ice spheres, but you don’t expect clear ice from these basic molds. Highly recommended.

The ZOKU Ice Mold Set is much easier to use than other molds that stick to the ice. I would buy this again, if I wanted to make more than 2 at a time.

I purchased the sphere molds. it's easy to fill and very easy to get the ice out. Will buy more.

THIS is the best ice ball mold I have found out of all the ones that seem to be sold. The only way one could get a better ice ball is by someone experiences in hand chipping one. Which no one seems to do anymore. There are some molds that come close however half of the mold is still hard plastic which makes removal more work. Zoku's version has silicone on both halves making removal a breeze. I suggest filling with warmer temp water rather than cold. You can use distilled if you want to be diligent but I have been doing fine with hot tap water. The mold shape is made with silicone so you might experience some slightly out-of-round shapes. This is not really something you would notice though. Each mold is separate so it is easy to fill and remove. The multiple sphere version molds are clumsy. *Every time I use this I remember my first whiskey lowball with a hand carved ice sphere.

These are the best ice cube molds we have used. They make perfectly round orbs. They are easy to fill and hold up well in the dishwasher. Would definitely buy again.

Solid product. Easy to fill, and easy to pop the ice out. Works great and I'm very happy with the purchase.

Its just perfect. Its the best product in terms of quality.

Fácil de usar, funciona, no se sale el agua ni nada raro. Al final tampoco se utiliza tanto porque sólo se hacen dos esferas cada vez, pero me gustan. Es cierto que se deshacen más lentamente que los cubos de hielo.

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.

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.
