Hedge trimmer

I have a bunch of hedges on the side of our house. They can be such a pain. I tried to level cut them and I'm always running off. The other day my husband bought me this trimmer thing, it looked right out of the sci-fi movie. It trims and edges but it also sucks up the pieces like a vacuum cleaner. It is called the garden groomer its from Harbour freight 97 total dollars including shipping.
