I've been using hot air popping machines for nearly 45 of my 65 years, and so when my trusty old hot air popper finally gave up the ghost, I looked around for a replacement. This is the one I chose, and I can only say that it was one of the worst experiences that I've ever had, and that it could have cost me my eye sight. This machine is, in my opinion, dangerous.
First of all, on the positive side, the machine has an on-off switch, something my old machined did not have. The corn it does pop is tasty, and the final advantage is that the looks of the machine are very stylish.
But I've returned the machine for its uncivilised habit of spitting out super-hot, un-popped kernels that often reach the bowl and explode, showering popcorn every which way and messing the kitchen. In more than one instance, I have been hit in the face with hot popcorn as I watched it pop. I wear eyeglasses, so no damage was done, but It would not have been a pleasant experience to have this happen while popping corn for the grand kids.
There are other concerns too. First, only about half of the corn that gets put in the popper comes out having popped, the remainder remains in either un-popped or partially popped kernels. My old machine did leave a few kernels un-done, but this one left way too many! The second concern is what I dare call build quality. The `dome' of the machine was not well fitted, and could easily be knocked lose, and the switch did not have a positive on off action: it felt a bit like I had better expect that someday soon, I would turn the machine on and nothing would happen because the switch would no longer work.
So, my advice, give this one a miss. I'm still looking for a good replacement for my reliable old hot air popper.
