Wasn’t expecting it to be real quality for the price, but it’s worse than I thought it would be.  the arms move and you have to balance them so it stays straight.  if one gets bumped it’s backed to balancing it again.  the one arm is bent out, and the cancel light part is way out.  Can’t bend it back to the right position.  Tubing is cheap and the installation was difficult also.  Not pleased at all,  but will have to do until I can afford better.
