I think it's a great way to be able to see shows on a budget. Seat locations vary, as was already said.
In the last 6 months, I was able to get tickets for Beebo Brinker Chronicles (off-bway), Country Girl (previews), Top Girls (previews), Sunday in the Park w/ George, Cry-Baby, Xanadu, November, [title of show], East 14th (off-bway), Spring Awakening, and The Seagull. In the past, I was able to get tickets for Rent, The Grinch, Curtains, Die Mommie Die (off b-way), Altar Boyz (off-bway), and more that I can't recall.
I check the offernings frequently. I usually find more tickets availble for Tuesday, Wednesday, and Sunday evening shows.
I don't think I ever got TERRIBLE seats and some have even been center orchestra. However, like the other poster said, if you are a seat snob, use a discount code and that way you get to pick your seat in advance. It will cost you about double for each ticket, though.
Hope this helps.
