Two guys, two ladders, and a scaffold put two of these up in an afternoon. The first one took a bit to figure how to drop the existing backboard, that's where the scaffold came in handy. The second one we put up in less than an hour! One thing I would recommend is getting some carriage bolts instead of the hardware provided, it makes it much easier to tighten bolts in close spaces.
The hoops work as promised, they are easily moved up and down! Glad we got them!
