I have several areas that need trimming that I cannot mow in so I bought this in the expectations of being able to sling cut the grass and weeds. From the other reviews I thought this would fit the bill but I am really disappointed in it. It will cut (actually it is more of just a rip and tearing) the weeds and does an even poorer job on the grass itself, but it certainly does not leave a nice appearance. This will be only used when and where I have to. It is brand new so the blade should be sharp but it certainly makes a mess of the area you use it on. Plus, it is a bear to use and I am very active and stay on the go all the time, yet using this for just a few minutes almost wears me out. If I still had the box, I would return this as I am very disappointed in it all the way around. I relied on the positive reviews but I sure don't know what they reviewed or if they actually ever used this product.
