Bests & Worsts Reviews from Amazon

The first several times I used this product, it didn't seem to work--the ice cream never really froze, it just turned into a very cold soupy sludge. I had checked all the obvious things--made sure the bowl was completely frozen, made sure my ingredients were well-chilled, didn't overload it and let it run the recommended amount of time. I was going to return it, but thanks to all the positive reviews here, I thought maybe there was something I was doing wrong. There was. For flavoring, I was always using a certain artificial vanilla flavor that I like. And because I like it, I use a lot of it. One of the main ingredients of this flavoring is propylene glycol. If any of you who read this are chemistry buffs, I'll bet you're laughing now. Propylene glycol is often used in food flavorings and colorings, but also is used as antifreeze when a non-toxic antifreeze is required. So I was pouring in a good deal of edible antifreeze with my ingredients--next time I'll just use chocolate or something! So, if you're having trouble getting your ice cream to freeze and you've checked everything else, make sure your flavorings don't contain propylene glycol!!
