Good product for the price
I bought for my Worx trimmer and they work great. Even though Worx offers free replacements, when you add shipping onto the "Free" order..it costs more...this price is well worth it.

String breaks about halfway
Just as pictured. PROBLEM…..LINE BREAKS ABOUT THE MIDDLE OF THE SPOOL…. Wound so tightly that once you have used the first half it is impossible to use the rest…. So guess what…I have to buy more!

FAST. Powerful. Easy to use.
Size: 8" Edger New
WOW! I bought a new house a couple of months ago, and the landscaping company overlapped the edge of the driveway with the sod. I've bee trying to trim it back with my string trimmer, but the results were less than desirable. I got my new edger today, and I am astonished at the results! ruler straight edging, 2 1/2" deep and 1/4" wide. PERFECT! . . . and the whole front yard took less than 10 minutes! The edger is very powerful - it easily cut through the sod, deep into the dirt underneath leaving a nice clean edge. My neighbor has a lawncare company, and he was watching me. He came over and said he was going to get one for his jobs, as it is much faster and easier to use.
