I paid a premium for your "commercial" patio heater for my home. I have used it 3 times and it's already deteriorating. I'm sure I'll get to use your "lifetime" warranty soon. Assembly was fairly easy other than removing the white protective plastic on the propane bottle cover. It came off in 1" pieces and left glue residue all over the tank cover. It took me over 2 hours using a heat gun the get most of it off. Very frustrating.
