As usual, before making a purchase like this, I looked at the reviews on Amazon. Mostly very favorable, 4.5 stars. But more than one reviewer said that the exhaust gets RED HOT, hot enough to set wood or grass on fire. Then another reviewer posted photos of the saw that had set itself on fire and was a blacked mess of melted and burned plastic. So, it appears to be a good saw with one very dangerous flaw. Thanks, but no thanks.
