This is a great little microwave popcorn popper that doubles as a bowl. You simply pour the kernels into the bottom up to the marked level, microwave for 2 to 3 minutes, and the bowl unfolds as the kernels pop. When done, pick up the bowl by the two tabs to prevent burning your fingers. It makes perfect popcorn with nearly every kernel popped. We like our popcorn fat-free (which is why I purchased this popper), but you can pop it with a bit of oil or add butter when it's done. We are very happy with this purchase!
I love the idea of a reusable popper but this one falls short. It's tricky to close the top and it often pops up several times before staying. It also flips open during popping with kernels going everywhere. And finally it's very hot when the popcorn is finished popping. Even the grabber handles are very hot.
