I have been running one for 6 years maybe longer. No problems at all.Stihl with straight shaft...
I've never added any additives to my craftsman. Good ol 87 octane and 2 stroke oil. Always run it out of fuel before winter, but that is it for me.You may already do this, but it must be pointed out that always running treated gas in your string trimmer is as important as the brand you buy, if not more so. Adding a fuel additive such as Stabil brand or similar is what I'm talking about. Doing that will have a significant impact on your trimmer's longevity.
