I just bought 3 of these heaters for my patio. My success with propane patio heaters has not been good in the past and I've thrown out at least 4 or 5 over the years. It looks like they finally got rid of the pilot light which was always a problem to light, and keeping it lit. Imagine my shock when I pressed the gas knob for the first time, hit the igniter and whoosh - we had heat! These units are good and hopefully will last.
