Query: I'm VERY disappointed

I'm amazed at how poorly this appliance works; I expect more from a product made by Cuisinart. The cannister took 3 days to freeze, and the ice cream it produced was grainy & had gummy, unpleasant lumps in it. We thought that perhaps since the canister was still half frozen it wouldn't take so long to freeze for the next use; this is, apparently, wrong. And the last two batches attempted wouldn't freeze. Anyone looking to buy an ice cream maker---DON'T buy a Cuisinart!
