I’ve also had one of these for years. If you use oil, expect the cups to wear out after about 2 uses. The problem is that after a few uses, the corn pops slower and slower. And that means the already popped corn gets burned. So you have to stop it before most of the kernels have popped. In theory, you should let it pop until the time between pops is about 2 seconds. Second problem is that the bowl is too small. To pop the amount of corn we need requires two popping sessions.
So I very recently ditched the Presto, and got a Stir Crazy II. I had the original Stir Crazy prior to the Presto. It’s big downside was that it was difficult to clean. Only the bowl could go in the dishwasher. That’s been fixed, with a separate heating plate that comes off and goes in the washer too. And it has a good size bowl. Works great, and the Presto’s gone in the trash.
