Alright HUGE question guys.......... heh On my trimmer i use these long plastic blades that dont break off when you hit stuff with them / the long plastic string that breaks off every time you hit something. These plastic blades were first advertised on tv, you guys prob know what i'm talking about and thinking what a amature.... your right. I'm just starting out guys so be easy on me My view of these little plastic things are that they are to heavy for most trimmers and will slow down rpm's. Spits back rocks/weeds back at me faster. They wear down every week so i have to change them witch is $5 for a new box of 9 blades. Have you guys herd of this toy.... i'm interested in your views of the product?
