I have a sandwich maker similar to this and a panini press - so this is a welcome addition to my kitchen fun. Super easy to use - be sure to follow the instructions and do not put cooking spray on this before making donuts. My sandwich maker had the same warning, and by brushing with olive oil instead of cooking spray, it's lasted for *years*, so I'm hoping the same will apply to this cute little donut maker. We've been having a blast making different variations of donuts - I'd best be careful, though, as this will throw my diet right out the window! LOL! Works like a charm - highly recommend!
