DLF Crest Gurugram: What's DLF's delivery record?

Looking for some real insights on DLF's track record. I just saw a walkthrough of DLF Crest, Sector 54 Gurugram. The project looks interesting, but I'm honestly more concerned about the builder's past. Has DLF Ltd. generally delivered projects on time? What's their construction quality like in older developments? Would love to hear about your experiences with them.
