This product blew my mind! I could not believe how well it worked, especially being batter powered. I ran through about 4 blend cycles and i know it could have gone longer. The ice was creamy and not chunky like a blender. It mixed the shaved ice into the cocktail a few times as it ran. If you like any frozen drinks, this is a 100% MUST BUY I even did margaritas on the beach with it!!!!
