This thing is good for your home if you dont have a lot of trimming to do. For anyone with a lot of edges or hard to reach places this thing is a piece of crap. As I do landscaping work, you don't want to go with anything other than a gas powered weed wacker, preferably a Red max. It's not hard to mix oil and gas, its simple math that a 4 year old could understand. It will save you tons of time, i.e. replacing string, and money i.e. it will last much longer. Final decision = garbage
