I liked the price and the installation seemed simple enough. Once I started to position my speakers everything went south. To adjust the 3 different nuts there is a tiny hex wrench that didn't fit well. On a ladder, reaching in to a corner by the ceiling, not an easy task. But okay, I thought, you get what you pay for. Then I started to adjust the position of the speakers. The first time I positioned them, everything thing seemed ok, but once I started fine tuning the placement, the nuts started to come out of the mount and I couldn't tighten them any longer. Cheap plastic junk.
