The idea behind this little machine is great, and I was super excited when I initially pulled it out of the box and set it up. I turned on the light, which lit up the "Popcorn" marquee and the inside of the unit, and thought "this is awesome!!1". The thing looked very authentic.
There were several downsides during actual use, however. The kettle size is 2oz - compare this to a bag of microwave popcorn being 3.3oz. To achieve a similar yield, you have to pop two cycles in this machine. The metal lid over the kettle doesn't stay up on it's own when filling with oil and popcorn, which is more annoying the second run after the thing is super hot. When the kernels start popping, several unpopped ones are propelled out of the kettle in the process (because the kettle is so small), dropping the actual popped amount to about 1.5oz. Somehow, a few of them also flew out the vents in the back. The light is listed as a "warming" light, but is about 25 watts and way at the top of the machine, and is ineffective for warming any popcorn not immediately taken out. All the walls are plexiglass, which is more difficult to clean than regular glass and will haze up over time. There's no good way to get the extra popcorn and kernels out of the bottom, short of shaking the entire machine over the garbage can. To remove the kettle for cleaning, you have to unscrew the side lever that tips the kettle entirely each time you want to take the kettle out. Combined with the small size of the metal lid on the kettle which is not easily removed, cleaning is kind of a pain.
This machine is an awesome idea, but after using it a few times, I ended up returning it to purchase a higher end machine with a larger kettle, heating element under the bottom deck to adequately keep the popcorn warm, and a removable bottom tray and glass walls to be more easily cleaned. This machine is a cool novelty item, but to get one where everything works without hassle, you'll have to drop a little more money.
