I bought this saw from Amazon (re-seller) and was pleased with it for about an hour. The chain would not stay tight no matter what I did and no matter how many times I tightened it. Also it was not very powerful and I had a hard time cutting down some 8 inch in diameter trees. Not too easy to start either. Good news is the re-seller took the saw back for full credit. I would definitely look at for a different saw. Some folks obviously like this one but I had a terrible experience. Is it really worth the risk and the pain? Nope!
