Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Junk!!!!!

This is a flimsy aluminum extrusion., If you plan on hanging anything heavier than a paper screen, find something else. The screws supplied are way too small. The track is also too narrow to fit a two door bypass. I doubt that anyone ever tried this hardware before they foisted it on Amazon's customers. Go to a hardware store where you can see what you are buying. Stay away from this junk
