The Feather Light Weed Eater is Great !!  I bought my Feather Light when the construction of my home was finished ... that was six years ago and it works like the day I bought it.  The gentlemen at Sears took the time to show me the Feather Light Weed Eater he instructed me on how to start it, how to mix the gas/oil, also a trick to mixing it.  I follow exactly what he said and it continues to work very well... I've never had a problem with it.   The Feather Light is just like its name... Light as a Feather !!
