This is a great little kit. The only reason I'm giving it a 4 instead of a 5 start is if you use them enough, like for a living they will eventually have to be replaced. I use them quite a bit and they work wonderfully. With this type of tool you use it in excess then you will at some point have to buy new ones. Dewalt is also a very good company to work with when you are looking for better tools. Good Product.
