Query: Trouble in paradise

I originally wrote a very positive review about this ice cream machine.Unfortunately, on my third use, the machine broke. When making a single batch, the motor would shudder or skip. It was almost as if the motor was binding up against something or was becoming jammed.So I had to return in to the store and exchanged it. I'll keep you posted on whether I have trouble with the second one or not.
