A very sad piece of junk. Had to file an extra piece of solder out of one tube to insert another tube section. Then I had to drill out a screw hole that wouldn't align with hole in 2nd tube. When I screwed the top section to the pole (which was easy), the large screw sheared off at the junction, leaving half in the base pole and half in top arch tube. Can't be salvaged. A serious waste of time and money. Should be able to choose zero stars.
