"...No tool chain tighting is the way to go..."

Does Poulan's really work? I have a Craftsman with the no-tool thing, and the stupid thing will not stay tight, I have to re-tighten it all the time. It is not just this one either, I have used other Craftmen that did the same thing. Been working with a Stihl the last month or so, it requires tool, but doesn't have to be re-tightened very often...
