Bests & Worsts Reviews from Amazon

No crushed ice and rock salt. It uses a double-walled container/bowl that needs to be in the freezer for about 24 hours for best results. Of course it will depend on your freezer settings and how much time it is out of the freezer. Your mileage may vary. I have "gotten away" with 12 hours, but the final product is very soft and it takes longer to make. If after 45 minutes the ice cream isn't ready, then the bowl probably didn't freeze long enough. Put it in the freezer for an hour or two. It will be just as delicious, but will be more dense. It's best to transfer the ice cream to a plastic container with a lid so it won't absorb freezer odors. Ours never lasts long enough for this to be an issue. Store the bowl in the freezer so it's ready for next time. While it is larger than the ICE-20, it's still only 2 quarts. I've found this to be ideal for spur-of-the-moment ice cream fun for just my family. However, don't throw away your larger churn just yet. You'll need it for parties. But because it is small, I find that I'm more willing to experiment with flavors since I won't be "wasting" it if it doesn't turn out right. But the only time that happened is when I used 100% Splenda. (If you want to save calories/carbs, experiment with one of the sugar alcohols like Erythritol or Xylitol. They yield a better tasting product with better texture.) Overall, I am very pleased with this product. It couldn't be any easier to use. Simply freeze the bowl, put in the mixed ingredients and 20-30 minutes later you have great tasting ice cream.
