User Review: I've owned this popper for 17 years and it's still going strong. It makes the best popcorn ever especially when you use solid popcorn popping oil such as CocoPop sticks (found at Smart & Final Warehouse store).  I also use the pre-measured packets that are made for theater type machines that you rent at party stores.  I drag this popper everywhere we go in our motorhome and have become known as "The Popcorn Girl" to the kids. I purchase popcorn bags (sleeve type) and the kids stuff them with a scooper.  It keeps them entertained for hours or until I'm sick of listening to the generator run!  I've replaced the dome lid once and the non-stick is beginning to wear off the ridge where the stirrer rotates, no big deal.  The base is well seasoned and the dome is broken again (my fault)but I can't bear to replace Old Faithful. I've given this as wedding and birthday gifts and it's always well received.
