Taj Mahal Night view reviews?

Hey folks, 1. I am planning to visit agra and i am wondering if Taj Mahal night view is worth it? I would be in Agra on 12th Jan Night. Should I get the tickets for the same? (Also please help, as the website shows tickets for only 11th Jan today) 2. The website says, Phones arent allowed, so is there a way to photograph it there - Are there cameras/photographers available there? 3. Any particular half an hour slot to prefer from 8pm - 12 pm to get the best view?
