I am a complete moron because the first time I tried this I put huge chunks of ice in the Sport Rocket Blender. I should have read the instructions first because it clearly states it is not an ice crusher. Anyway, I tried this out a few more times to make yogurt smoothies for my daughter with NO ice and it worked perfectly! You can still add ice but it needs to be in smaller pieces. I even made non-dairy/no sugar ice cream with this! I love that I can just quickly blend up a smoothie, flip the tumbler, switch lids from the blade to the to-go lid, and walk out the door. It makes my life much easier when I'm in a hurry and have to get some nutrition in for either me or my daughter. I also love that the Linea Rocket Sport Blender doesn't take up a bunch of counter space. I need all the counter space I can get! The colors for the Rocket Sport are fantastic, as well. I wish I had the orange one instead of red to match my kitchen but the design is still pretty slick and modern looking.
