I bought this chainsaw via amazon over 2 years ago, and it's still going strong. Saw starts first time, everytime. Have never had a problem with it yet and the only thing that has had to be replaced has been the air filter.
Still using the same chain and bar that came with the chainsaw, although I have been told from the last time it was in for a servicing it could do with a new chain (sharpening the chain doesn't keep it going forever but does help with it's lifespan).
Saw is supposed to get a service for every 10 hours of continual use, this is more for your safety and keeping to chainsaw in tip-top shape.
I would of gave this chainsaw 5 stars, but the chain oil leaks when the chainsaw is idling. Have to say though this doesn't happen when the saw is in use ONLY when it is idling.
If your only using this saw for small jobs or occasional use then I'd have to recommend it, but for any bigger jobs then I'd suggest spending that bit more and buy something else.
