I bought this to replace my heavier 4 stroke string trimmer, starts easy, good power, and brings back memories of motorcycle racking days with the smell of Blendzall bean oil at 32-1. I don't have time to ride dirt bikes much these days, but at least the smell brings back cherished memories and the yard gets more attention. Yeah I know it should be 50-1 echo oil and I have probably voided my warranty :P
