I bought a Stihl ht131 polesaw a few years ago. I had never heard of a 4mix. The dealer never said anything about it. If I had known it, I wouldn't have bought it. It does an ok job but I have never been fully satisfied with it. My father in law has an echo and it is a much better saw than my Stihl, for close to the same money. I bought it spur of the moment without doing any research. I was bushhogging and got tired of getting hit in the head by limbs so I got off the tractor and went and bought it.
