They're on about 50 launches, and about 40 with regular payloads rather than their in-house capsule. The second stage and payload deliver has - to date - a 100% success record. It's a great bit of kit. The failures have been first-stage related, thus far, and now possibly customer-adapter related. I can't comment on how many other non-capsule launches have custom adapters, but SpaceX do make and use their own usually. To a first approximation, maybe 10% are non-standard?
