Based on 0 ratings to complete the project on time. They arrived at noon and I immediately opened them and examined them. The fit and finish were as good or better than the LSI slides I usually get. The ball bearing guides worked well and were smooth. The initial opening and subsequent closing/latching were tighter than I'd like, but they should loosen over time or you could shave/file the stop. Of the 10 pairs of rails, 7 fasteners and only 6 cheap, easy-to-remove screws are included. I dropped them after the first few pairs and just used my own hardware. I think I'll go back to the LSI slides as they cost the same but if I need 10 day shipping I would order them again.
