I am not a professional lawn care guy, just a home owner tired of sucking up lawn trimmer smoke and going deaf. I am looking for a reliable battery powered lawn trimmer, can anyone point me in the direction of a decent machine? They are all about the same price in the store ><$20 difference. I have not picked one up that is anymore heavy than my trusty old 2-cycle. I am mostly concerned with battery death. Thank you in advance.
