Used for the first time in 40 and below degree weather. If you want to stand around the heater, it's fine for keeping upper body warm. Once you sit, it's a little far for the heater to warm you sufficiently. I plan to remove about a 2 foot section out of the middle of the top pole the weld the 2 pieces of the pole back together. This will bring the heating element closer to the ground to heat bodys sitting around the heater and avoid standing all night. Hope to report back how this helped the performance but almost positive it will. The quality of the assembly directions are good. The quality of the heater and other parts seem good.
