I received this as a Christmas gift. I've made at least two slushies per day, with great success. Soda slushes are OK but lose some flavor and the carbonation during blending. There's no way to avoid it since it's science at work. My favorite slushes are limeade with a capful of lime juice, to give it some kick. The guides on the side of the cup work well. I've had an equal amount of success filling the cup with ice first, then adding the liquids. The only downside is I haven't seen the blender or any accessories in stores. I want another blender just in case I burn out the motor!
