I love air-popped popcorn, but this popper definitely doesn't deliver. I'm not sure if it's because it is too short, of because of the angle of the lid, but I can only get about half of the kernels to pop with this machine. The others fly out the top before they get hot enough. I haven't had any trouble with the popcorn burning, and the machine itself seems pretty durable. I have, however, wasted a lot of popcorn just to try and get a full bowl. I'm not impressed with this model, and I will be looking for one that is taller next time. I got this one because the price was right, but I think it might be worth it to spend a bit more for a better brand or style.
