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.

Needs improvement
This trimmer really looks nice and it comes with some great attachments but what I found is that if you're going to switch from the line attachment to the little plastic attachment you have to sit somewhere where you can lay the item down because you have to unscrew one to put on the other. There is no way to easily switch from line trimming to attachment trimming without using the device that unhooks the screw. In my opinion that is really a detriment to the beauty of the overall working of this item the weight of it is good, it cuts good it automatically feeds the line out the color is nice and the price is great but then you have the issue of changing the line back and forth if this was improved I think I would definitely give it five stars I'm sorry but improvements need to be made.
