Greater Noida RERA is more show than substance

Is RERA just for show, or does it actually protect buyers from builders like Uttam Steels? My wife and I are looking at a 2BHK in Greater Noida West, maybe MMD Provica Homes, now that the kids are out. We’re selling our big place and want something manageable, near a good hospital. Everyone talks about Jewar airport’s potential and rising prices, but nobody talks about the real legal headaches if things go wrong. How do you actually verify a builder's legal track record beyond just RERA registration? I'm worried about project delays. Is filing a RERA complaint truly effective, or is it just endless hearings? I feel buyers are still mostly on their own, even with RERA. Change my mind.
