I purchased a trimmer/edger battery operated - the string keep rolling out and stopping the machine and the other attachment the green blade wore off in 3 minutes. I visited a local home depot to make sure that i am doing the right thing and I saw that the green blades is replacable - so I bought apack of it and when I came home to fix it - the green blades are riveted while you seeling replacement for non revited blades. I hate to create arguments at the store because they have incompetent people working there. All I need is an updated trimmer/edger - I just purchased mine 3 days ago - if you look at YOUTUBE - someone posted a review of the quality of the green blades. I need an interchangeable equipment where I can change the blade taking a screw off and insert a new cutter - my name is Sammy Chunasamy at 18401 Henley road Jamaica ny 11432 cell [protected]- i will not go to home Depot- send me a replacement and also a return label so that i can ship you the inferior item. You have great items - fix my issue.
