I Purchased this back in December and still haven't been able to get this to work correctly. Sure, the Ice cream maker will mix up everything when the "PRE" button is pressed, but we were not able to get the "pro" (only other button on the device) to work. What the "PRO" button is supposed to do is mix the ice cream mixture in the bowls at regular intervals while the device is in the freezer -this way you won't end up with a frozen block of whatever it is that your making while it is freezing.Wish I could say that this device did that - nope, the button light would be lit, indicating that it was ready to do it's job, but each and every time the ice cream maker was put in the freezer - the "ice cream" would end up never having been mixed, just one solid, frozen mass. We've tried "fresh" batteries and still no luck with seeing any attempt by the machine to even try to mix anything after the "pro" button was set. Opening up the device to see what might be the problem didn't offer any clues other than the insides are pretty basic and the circuit board made by cnnbst (?) is another cheap, useless product from China (why expect quality?). Anyway, save our money or think about spending it on something else that actually works. Even if you are lucky enough to get this thing to work, don't expect it to last long. Wish I could rate this less than I did since I can't get my money back or the time I wasted trying it.
