This blender was going great when I was making smoothies with fresh fruit ... however, when I tried making them using frozen fruit, the motor stalled and didn't blend as it should.  I assume that it just doesn't have enough power to work with the frozen fruit.
The name quiet blender is a bit questionable - I thought it was very loud, but I don't know what type of blender it was being compared to ~ so, it could actually be quieter than something else. [This review was collected as part of a promotion.]
