OK, I've dealt with a fair few too many echos in the bush over the years, for hard-out, full time use they never make the grade, end of story. They're cheapish casual use saws, that's the market they're aimed at. Any pretence of being commercial grade is just bluster and posturing from the company. Their 5 year guarantee is a sleazy gimmick, plain and simple. Here in NZ, as commercial saws they're ridiculed with a vengeance. The ones that don't blow their engines and actually last for a while are so detuned and sluggish it's pathetic. I've seen them drop-kicked over cliffs and hurled into rivers. I've seen piles of them dumped into the back of work vehicles in disgust, never to be pissed around with again. Lots of bush workers never listen till it's too late. The glossy echo brochures do their trick. Give most echos a full months work, they'll rattle, vibrate and run like sick tired dogs. The equivalent stihls and huskys are only then just getting into their stride, responsive, smooth, barking and powerful. Running a stihl or husky after running an echo is like shifting house from a leaking corrugated iron shanty to buckingham palace. Even the latest model echos I've seen crap out in a big way. Nothing seems to have changed. Again, as casual saws they'll do their job, anything will actually. Waste of time comparing them to the top brand saws though
