So far I am very pleased with its performance. It does tend to leak some bar oil since last use. I have not looked at cause of leak. Thinking I may not have got cap on oil tank tight enough. I have cut down 2 trees with it and cut them up within the last month with no issues.

Hey Bud, thnx for the video, appreciated! Whats your take on the 3900 saw after using it for a min.?
