..that you actually liked? I was head over the heels for the Magic Bullet blender, until I used my boyfriend's. It was horrible. I put in some peppers and onions to make a paste and it didn't even cut up the skin on the peppers! Has anyone had a better experience with this silly contraption? What about something else? Maybe knives that actually cut through pennies? The newest miracle exercise machine? What did they sell you on that actually panned out?
