A simple, one button operation & ice cream is ready in about 35mins; yogurt/gelato, in about 25mins; just pre-freeze container, pour mixture into canister and turn dial on; is a little noisier than anticipated, but for the ease of use & price, it's hard to beat; wish it had a pre-set timer to stop when done, but using the kitchen timer worked fine; very pleased with it & would readily recommend.
