ATS Pristine Golf Villas: What's ATS's delivery record?

Watched this video about the ATS Pristine Golf Villas in Noida, Sector 150. Wow, the 500 sq yd sample villa looked amazing, really luxurious! It got me thinking about ATS Infrastructure though. I'm trying to gauge their builder credibility. For anyone who's bought from them before, how's their construction quality and delivery? Do they usually stick to possession timelines, or are there common delays? Would love to hear real experiences with ATS projects.
