I have the excellent, highly recommended light-weight LXT set with drill and impact drivers, and wanted a tool for close quarters. I chose this impact over the drill model as I like the fast (unfeelable) tapping that more easily drives screws and removes them. Be aware the other right angle drill has a manual chuck that needs a key handy and this unit only has the hex configuration with collet, so the owner needs the type of pop-in hex bits for drills and screw types most common today, which are superior and not hard to find (requires no re-tightening like the collet type). Very comfortable, nice light that shines where you are working, easy to use, very small head design, fits in small places, well balanced and great name for quality tools. I find I use it most of the time; comes with a handy belt hanger.
I highly recommended this tool and it is nice to use the same battery as the LXT series (comes with no battery or charger). Instead of having a variety of drills and batteries to re-charge and keep track of, this goes well with the LXT series and keeps it simple. It is a very nice addition to my tools for the DIY'er that I am, and likely great for a professional as it feels very well made and has a low profile for tight spaces.
