Pros: Extremely effective at cutting through thick trunks.
Cons: High Cost
I bought this with only the saw blade to tackle very very thick dense brush that ranges from 2 to 10 feet in height. I tried it on a small bush first and was amazed at how easily it cut through the 3/4" diameter stems - like they weren't even there. On to the jungle - this thing cuts through silver dollar diameter trunks in the blink of an eye. The engine has been very good starting (just one day). It really revs to a high RMP for a 4 stroke. I've had no problem with the engine. So far, I'm very pleased with it.
