When buying tickets on Songkick I felt no (negative) difference with my experience via other websites like Ticketmaster or Seetickets. The process was quick, the site intuitive, it didn't have any problems loading and I would happily use it again. If I could make one suggestion it would be to allow users to save payment details in order to make the next transaction even quicker but it's not a massive sticking point. I will definitely be using them again!
