The impact gun is more powerful than my Snap-On equivalent (which was only 7.2v and cost 3 x the amount!) the Titan one has a progressive trigger and LED work light. The impact gun is a bit driver really so I bought some impact bit to socket adaptors whilst I was at it so for an extra few quid it will now drive 1/4", 3/8" and 1/2" sockets.

I've also found the SDS Drill and Circular saw from Titan to be very good for DIY use.
