Purchased this for my Mom for Christmas. From what I could determine from product and consumer reviews this was a good product. My Mom and I both tried it out as soon as received. It has easy to follow instructions. It is easy to use and clean. Note: not dishwasher safe. It popped all the kernels. It does use oil in the base. It has an arm that mixes the corn and the oil going in one direction than the other. It has butter melting capabilities under the top cap, which you have to leave the cap off while popping the corn. It will melt the butter and mix it with the corn while popping. How cool is that? The only thing my Mom I did not agree with the instructions, is how much butter to use. We thought the batch needed more than the instructions called for. So we added more butter and plugged the unit in for another quick spin. Voila!
