I purchased two of these for use in a Boy Scout Troop. I couldn't believe how shaky they were when I first set them up - there is literally no support for the tree except where the bases rests against the tank. Probably the third time we used them we had one set up near some tables the Scouts were sitting at when one of the boys swung around and hit the tube with his arm - not terribly hard either. The plastic knob at the bottom sheared off and a jet of propane shot out six feet before the tank's cutoff engaged. I have thrown both these hazards away and would never recommend them to anyone. OSHA would have a fit if they knew abut this product's safety problem.
