I bought a Felknor popper about 20 years ago. It is still going strong, I passed it on to my son. I tried to find a replacement, could only find Whirley-Pop. The first two were very short lived due to the poor attactment of the gears to the shafts. Also, I could not get a response to our complaint by the manufacturer in spite of the guarantee. I finally bought a third but only because I needed a popcorn fix and I first inspected the thing in the store and found that the gears were now pinned to the shaft. I'm not happy with Whirly-Pop the company, but I am have good popcorn.
