Bought mainly to do smoothies. Crushes ice and frozen fruit adequately. I do notice that sometimes protein powder lumps but not a big issue. Dad not real like others though you DO have to screw the blade lid on TIGHT and it is easy to get crossthreaded.
I bought this about a month ago and use it at least 3x a week for smoothies. So convenient and doesn't take up too much room on my counter. Blends quickly and perfectly smooth, I love trying new recipes from the app too!
