I didn't expect it! Indeed, the ice cubes come out spherical - useful if you don't want to empty half of your ice tray into your coffee with regular ice cubes because here you put 3 - because they are big - and you're good. I'm not used to the way you fill it because if there are leftover ice cubes in the ice tray, the lid doesn't close properly so you can't refill it, you have to empty the whole ice tray. Nevertheless, the ice cubes are very stylish and useful!
