Well, my review will be incomplete for now. Why? Because it was delivered without an adjusting screw for the ignition nozzle! Came with an Allen key for the screw specified, but I can't use it without a safe pilot bit. I think you get what you pay for for a large diameter hole saw. In addition, quality control needs to be strengthened. The color in the thread made it very difficult to fix the pavilion. I'm putting it on and will be browsing my local hardware store for a set screw to go with it. I may change my rating after it's up and running but right now I can't recommend it due to the crappy quality control.
