I ordered 2 of these fixtures to go on the wall in our bar. The first one was installed with no issues, the joints all have tension enough to be positioned and stay. But for the second, the middle joint is loose and the arms would not stay where needed. The electrician tried to fix and ruined it, so I ordered 2 more (because we have one installed already so we're committed) thinking at least one of them would work but neither did. Same issue, the middle joint is too loose on both. This time, I bought some super strong glue and just glued the joint myself. They have not installed yet, hopefully this will work. This is probably not an issue if the fixture is going on the ceiling but definitely is if hanging on a wall. Another reviewer mentioned brackets were included so the manufacturer must know about this,  we did not have them in any of the boxes.
