I looked at several competitive products and chose this one.  This is a very good tool.  It is easy to handle as it is light, yet powerful, and the trigger is large.  These features give you good control esp with larger screws.  I have driven up to 3 inch screws with ease.  The nosecone takes some practice to adjust, but once you figure it out, it performs very nicely.  My only complaint is that the instructions provided are kind of sparse and you end up figuring out how to use the tool by yourself.  Not a big issue, however, as the tool is very simple.
