What's the real deal with ROF Group projects?

Okay I'll be honest — I work in real estate but buying my own place in Gurgaon feels totally different. Everyone glorifies new launches, but what about the actual delivery? I'm looking at ROF Insignia Park 2 on Dwarka Expressway. I know the super area vs carpet area games builders play. What's the real word on ROF's construction quality after possession? Any hidden charges I should watch out for with them, beyond the usual PLC or registry? I hear mixed things about their reputation post-handover. Change my mind if I'm wrong about their transparency.
