Realty Vision Infrazone: Sahi hai ya nahi?

Guys, I'm planning to buy a 3BHK near Sector 75. Realty Vision Infrazone ka project Realtyvision 4th Avenue dekha. Has anyone experienced their on-time delivery? Construction quality kaisi hai actually? Wife wants a good society, safe for kids. Kya kisi ko hidden charges ka experience hua hai? Mujhe advice chahiye, bhai. Don't want any surprises later. Is it worth investing there? Pls help!
