They're just like cars... everybody making them ends up with models that are lemons, and models that are really nice. You can call anything
professional, industrial, superior grade... as far as truth in advertising goes, it's all considered "reasonable exaggeration" and they all do it. You'll never see an OEM call their product
total piece of crap or
only suitable for leaving on a shelf in the garage. They don't make commercials telling you that their product is really just worthless junk that only an idiot would actually buy. No matter how true this may be, you aren't going to see them advertise it.
If Echo made all of their products like the cheap crap the home improvement stores and Walmart sell, then some serious bashing would be in order. Echo products are clearly the top of the line that is offered at most of those places, and Echo doesn't claim that their lower priced products are the best they make. That's well within what you would expect from an OPE maker. So many professionals use their products that it isn't any wonder they call them professional grade... they hold up just like everybody else's so called professional grade stuff. Their power pruners (pole saws) hold up better than everything else out there... including Stihl's HT-131. Don't ask me how I know this, just trust me on this one.
I like to poke fun at lots of other brands of OPE... but that's pretty much all it is... a chance to rib people I don't know about stuff I don't care about. Well, except maybe Sears Crapsman stuff. Making fun of that junk is serious business.
I'm not sure why anyone would expend so much energy badmouthing anybody's product line over something as inane as a perceived conspiracy about specifications or plastic that "feels cheap" to them. Buy some damn Echo saws and smash them in a hydraulic press, right alongside a few Husky saws, and some Stihl and Dolmar and Poulan saws, too. I cut entire trees, everything 1" diameter and up, into firewood/kindling all day long. Run all those saws alongside mine, we'll see who starts cussing and swearing at the saws first. We'll do it on a 97*F day, just to see which saws are the real "professional" ones. It will end up being the ones that are still running and starting fine at sunset.
Just sayin'.
