Anyone used Seat Geek?

Did a search and didn't see anything, but apologies if this has been covered before. Has anyone used Seat Geek for secondary market tickets? Trying to score Hamilton seats and getting way too obsessive about cost and potentially getting scammed so I wondered how reliable they were. Ticket prices are comparable to ticketmaster resales, but you save a ton by not paying the fees that ticketmaster tacks on.

Just wondering if anyone had used them and if you'd recommend them. Thanks!

Yes, Haterobics, exactly. I haven't used the site for theater tickets but have used it for sporting events and it's an excellent way to get a true sense of secondary market value. Good site.
