I ordered this to replace the ceilings in a couple of rooms in my house. After comparing the price of this unit to renting, I decided to own it and not deal with driving to town and having to deal with a rental. It was pretty easy to assemble, the upright was a little confusing, seemed to slant until I noticed there was a retaining piece I wasn't getting the upright into correctly. The wings are the only issue, they slide in and are just held with gravity. I needed to flip one piece of drywall around to get it up against a wall and when I brought the elevator back down the arm fell out and hit me in the head. For the price and the fact I'll probably only use it a few times it was worth it, just be aware of the parts and they just slide together and may fall out if rotated certain ways. I finished one ceiling, it will be a while before I need it again, but I'll just store it and keep in handy for other projects. Overall, it did what it needed to do, it was a little awkward to work with, but it was better than trying to get people to hold the panels up while screwing the sheets down. I was using 4 x 8 sheets, the edge dipped pretty far before getting them up to the ceiling, not sure if this could do a 4 x 12 sheet, it would probably work but it would be wobbly at best. Overall, I was able to complete the project and it served it's purpose.
