I thought that the ice cubes it produces are large in size, but I wasn't too impressed either... they come out just fine though. It's good

The product is good, it does what it says. There is a difficulty with the water overflowing. I'm not giving it more stars because it doesn't offer anything more than classic ice packs of this size, so there is a cost issue in relation to benefit.

The size is ideal for a whiskey glass. Simply to fill it because it is silicone, I had a difficulty at first but the trick with the rubber band was the solution!

Very good material. To easily achieve balls, I use rubber bands to hold the cap and prevent water loss, and I use a syringe to fill them (48ml per ball). The size of the ball is satisfactory.
