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.

This can do some cutting
So glad I purchased this for cutting thin annoying vines and really tall weeds. The resin blades have held up to cutting 1/2" stemmed vines, weeds, and tall johnson grass out on the farm. Have not had to change out the first set and it comes with 3 sets of blades, plus an allen wrench for changing out the rotating head to a wire weedeater. Very happy overall. Too, it is not heavy at all, and noticed the battery lasts longer compared to using the B&D 20v line weedeater .

Very nice for the price
They’ve thought of everything for this. Easily switch heads. Easily change from trimming to edging. The line auto advances keeping you going when many others make you stop and make adjustments.

Faulty Trigger
This was the 3rd of 4 B & D Weed Trimmer's I have purchased in the past 4 months. My first B & D Weed Trimmer was purchased 3 years ago. The Trigger finally gave out. Every B & D Weed Trimmer has had a faulty trigger. They give out just past the 30 day return window - trying to get B & D to cover it on their warranty website is ridiculous! No one at Amazon knows anything either. So you either buy another or go to Ryobi...because you cant find any decent replacement blades for it either.
