Query: Awful

Very difficult to figure out. I'm pretty sure it shouldn't have worked with our projector, but after several hours we made it work using our own tools and screws. The directions have very few words and include pictures of parts that are different from what's in the box. It is very shaky on our ceiling. We tried to order an extender pipe to bring it down from the ceiling, and it only comes in black, even though are mount is silver and they are made by the same company. Also, the extender needed a pipe coupler, which was not included, and I can't find a place to buy it anywhere. Why would a company make an accessory product that doesn't connect tot he original product.
