bought as a gift for my daughter...worked as described. A bit noisy she said, but they watched a half hour tv program, tossed it back and forth and it was done. enjoyed it!
We used half-n-half, vanilla, sugar and some cherries. Loaded the "cold" side with ice and sea salt. After a good 30 minute workout, we had ice cream....and it was really good! I do want to stress that you have to WORK for your treat. The ball gets pretty heavy after about 20 minutes. I also suggest following the instructions. We used sea salt (added extra as indicated) and I had my husband buy a bag of ice. If you plan on using cubes from a standard ice tray, forgetta 'bout it! The cubes will be too large to fit in the chamber unless you crush them first. Also, don't forget to stop after 10 minutes and drain off the excess water, add more ice and salt. Overall, a good family activity.
