I always have had good luck with Oregon motors also. 5th star will depend on its longevity. You need oil- it doesn't come with any. No problems with power, or stalling. For the price though it's a great deal.

Oregon 572625 Final Thoughts
"I live in a forest."
It cut through like a knife through warm butter. With that there are always compromises. This little chainsaw is a Powerhouse. I used the battery from my Oregon weedeater. Oiling, on the other hand, is kind of weird.
