Used twice recently for two events. The first event was standing only, so was able to get a good view provided I turned up early and was prepared to wait.
The second, was at the O2, for which only the high far away seats were available. When attending the event, there were plenty of nearer seats available which I assume, ticketmaster was able to sell, so ended up with a poor choice of seats.
Each time, tickets arrive correctly and on time.
