Sometimes the ice cracks but ill have to figure out if it has to do with the temperature or location within the freezer

These work well sometimes the ball breaks in half but even when they do they still take quite a while to melt

The resulting ice ball freezes faster that way and is more structurally sound

The only bad thing i can say is that my ice ball cracked in half around my 3rd glass

The shape doesnt significant affect the purpose of a single large piece of ice

Im also using filtered water from my refrigerator and not distilled water or boiled water so that could be part of it as well
