It went though them all rather easily. Luckily I haven't had to use it yet. Used on a tree that fell in my yard. Lasts 3 - 4 hrs and have used it 5 times so far. Also, I dont like how you tighten the chain.

WORX WG309 Final Thoughts
"The saw itself isn't bad."
It was extremely easy to put together. When used correctly, it seems pretty unstoppable. Ordered this saw and arrived within a few days. I think it too was broken or the chain was dull. The first job was a trash palm tree.
