                it does what it's made to do! used it to make a flower bed and it turned out great. I like that the head was a little wider so it didn't go all the way through the thinner corner peices.

                I purchased these to attach foam insulation to a interior garage door. They worked extremely well, very sharp and penetrated the alum/steel easily with little effort. I am sure I will find a lot of other uses for this product.

                Great Item, saved the day. I was installing chicken wire to use as a gutter guard to keep the leaves from clogging the super gutter. see picture below. This had a wide enough head to grab it, make it's own hole and finally keep the chicken wire from coming up. I just had to figure out how I can do this, and did it.
