I bought four of these for my tasting room patio space, Due to Covid-19 restrictions, we needed more patio heaters in order to remain open. The glass tubes are decorative, they look good without pushing too much heat upward. They don't give off massive amounts of heat. Assembly was simple, I did it myself, only needing help inserting the glass tube (fearful I might break it if I didn't have spare hands). All in all a good patio heater.
