4 years ago I could not decide between electric edger and weed trimmer or a gas power head. I went with the electric...I bought the craftsman weed wacker and a separate hedge trimmer(both used the same battery), and a black and decker 12amp electric grass edger. The batteies for the Craftsman system would run out before I could finish the yard. Once the batteries were used they took a long time to cool down before they could be recharged. The 12amp black and decker grass edger was ok, it took a long time!, needed lots of extension chords but would eventually got the job done.With this product, I had to do a little more mixing(fuel/oil) and pulling(starting the power head for the first time was a challenge) but the end result was simply better.I haven’t had to change the weed wacker line yet, but seems simple enough. It got the job done!The edger. Awesome. It had all the power I needed, way better than the 12amp electric edge trimmer.The hedge trimmer attachment was very expensive and I did not buy it.I went with a craftsman system that married with my new drill battery set up. I haven’t used it yet. I’ll keep you updated.
