When I looked at the reviews for this product someone said the staples are good but the Phillips screws are not. He said his cordless drill ripped off the tops of the screws and you can use them with a standard screwdriver. All you have to do is set the speed to low and when the screw is tight move on to the next one. I checked hardware stores and this product is about 45% cheaper and better. I will be ordering more supplies for my next project!
