My two pennies, I'm 5'11 any cheap or even expensive curved shaft trimmer is to small always bending over when I was using them. Stay away from the cheap craftsman and poulan's unless you enjoy a pre-work out trying to get the pos started. When I lived in the city bought a poulon "pro" had interchangeable attachments. In order to get it to run halfway decent ground off and slotted the carb adjustment screws and housing around them. Eventually worked for trimming around my exes flowers and in the end did a great job on the actual flowers themselves. Lol.
