i purchased ryobi weed trimmer (model #700r) on sale about 6 yrs. ago. at 1st i wasn't sure of how it was going too meet my need as far as the size(31cc). well i 'm still quite pleased with the trimmer. my only compliant is rewinding the line.i buy a spool because it's more economical for me. it always seems i have too take off the spool and rewind at least once before it runs out.
