15 Pack (WA0010)Replacement Trimmer Line Spool C
This weed eater trimmer line is pretty tough. Although there was only 12 spools in the box, but the Description says 15 spools, And this trimmer line is a lot tougher than the previous line I was using. I used very little of it on the first spool, which is great these Worx trimmer line spools fit perfectly and function perfectly this is a great product to purchase, and I will highly recommend them. if you just have a small amount of weed eating to do I would recommend getting these spools for your worx weed eater.

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!

Light weight and very functional
Incredibly light and functional, this trimmer forks with either string or resin blades. I personally prefer the blades. At the time I bought the unit I couldn’t locate replacement resin blades. I finally called Black and Decker and they sent me two packages of the replacement blades for free! The shield keeps trimming from being a messy horror show. No more back soreness because of the ligh weight of the unit. I’m very pleased with both the product and Black and Decker.
