The apartment I live in has a concrete slab on the back patio, but no sort of cover whatsoveer. I've always thought about getting some kind of cover, canopy or awning, but really never did anything about it until I came across this. It was exactly what I was looking for. The perfect dimensions to fit over the patio slab, perfect height to match my patio door, etc. Setup and install was pretty straightforward. Everything just kinda slid, snapped and screwed together. Took about 2 hours when all was said and done. We ended up putting the top of each pole into the edges of the patio door track. Not perfect but it's working out and holding stable. Looks really great, functions well. The hand cranks move the awning smoothly. Easy enough to fold up when not needed. Still debating about leaving it up/installed over the winter or partially disassembling and storing until spring.
