Recently purchased and installed this heater on a semi-outdoor patio in Denver.  The patio has a ceiling and 3 walled sides.  One side is open to the weather.  The heater works fine in taking the chill out of the weather.  However, its heat range is limited and you need to sit fairly close to the heater to feel the warmth.  It is more convenient and less bulky than a propane heater as it requires no tank.  Assembly took longer than expected, approximately 90 minutes, even though I’m mechanically inclined.  This was mainly due to the number of parts involved, safeguarding against potential scratches during assembly, and instructions that could have been a bit clearer in certain sections.  There was no damage during delivery as the unit is well packaged but I wish they would find an alternative to styrofoam as it creates a mess.   I’ve used it for 3 days in Fall weather so far.  There have been no issues and overall I’m pleased with the product
