Noida projects: Post-possession quality concerns?

Did a site visit to Krishna Residency last week, and it got me thinking. I work in real estate, but buying for myself, the reality hits differently. The sample flat always looks great, but what about actual construction quality after a year? I'm worried about seepage issues, flaky fittings, stuff that kills resale value. And those fancy clubhouses... are they actually used, or just a maintenance drain? What's the real story on amenities vs. what's delivered? Does anyone regret paying premium for amenities that became ghost facilities?
