Set of 4 XL 5cm Sphere Round Ice Ball Maker - Large Silicone Drinks Mould by FLOW Barware

The sphere's produce great ice balls but there is a problem in getting the sphere to seal and not leak.Once mastered good product.

When they work they are great!! But sadly the thread on one of the 'balls' would not engage and so it leaked and could not be used.

These are great. They click together to seal the water inside. You have to be careful not to squeeze the sides otherwise to loose water. I put them on a litter tray then carry the tray to the freezer. The ice balls pop out easily and give better cooling to your drinks because they're bigger than usual ice cubes. Easy to use.

These individual ice balls are great! Good size for a gin Copa glass or whisky highball and the ice lasts for ages. I like the fact that they are individual balls, so don't take up as much room in your freezer as a tray with the same size balls would. You can just store each one wherever you have a small gap. You DO need to make sure they are totally flat when you first fill them though and be gentle when filling to the top, as it's very easy to squeeze them and the water will leak out before you get them in the freezer! Only purchased 1 set of 4, but I will buy more as they will be great for parties - saves making up so much ice!

Bought a pack of 4, the all leak. Tried wetting the seal and tried drying the seal. Nothing works

Bought this to create large, round ice cubes. Initially they worked fairly well. Sealed well but can be difficult to remove once iced - definitely need to run under cold water to separate from the silicone moulds. However over time, they leak more and more, so much so the most of the water froze in the freezer and you would need to clean the freezer often. Eventually stopped using it. Great concept, poor function over time.

Great quality easy to use and as they are individual moulds they are eady to fit in tight spaces

This is the second set we have purchased. They are great quality and work really well. Woukd not be without them now. Large ice balls look great in a balloon gin glass. Highly recommended
