We ran into a snag with corrupted downloads. Contacted the developer and within 12 hours he was totally engaged in the problem.
Really refreshing was how well he listened to what the issue was and dug right in to finding a solution.
Turned out the issue was subtle and hard to track down. The developer stayed with it until the mystery was solved and we are up and running! If this extension and the service I got from the developer are any indication of the quality of Trinitroinc's other offerings, buy them! You won't regret it!
