this machine is not designed to crush solid ice cubes. but if you brake the cubes down to a smaller size, it work just fine. its blends everything very well.
I am extremly happy with my purchase, the only negative thing is that the large cup broke after a week's use. One of the tabs that turn on the machine chipped off, so I can't use it anymore.
Great product so far! So simple, compact, easy to use and clean. So much better than the juicer we used to use! One suggestion would be to have the "MAX" line more visible or written larger. After all of the ingredients are added, it's kind of hard to find it (especially as you get older!).
