This machine is expensive when compared to blenders, but there is no comparison at all.  
This machine makes the PERFECT drink every time.  Slush like concoctions that pile up high due to them being so thick.  
I make margaritas, strawberry daiquiris, hurricanes, and more.
My friends are all jealous, but happy I invite them over for a frozen concoction every now and then.
I also like the pre-measured bottles.  I thought it would be a pain making drinks for people, but found that if I pre-measured the drinks out in the bottle, it is ever so fast and easy to whip up several drinks at once.
