I bought one of these sets several years ago for about this same price (which was as good a deal then as it is now). This is an amazing tool, quite reliable and perfect for most home users. Will take quite a bit of mistreatment and still work just fine. Before all you field mechanics and metal shop workers jump on me that it is under-powered just remember the target user here the occasional weekend project or someone who needs a frequent use of an electric screw driver with more torque than those 3.6 - 7.2 rechargeables (that just look like a fat manual screwdriver).
I like that because it is Li-ion if I can charge it up , make light use of it, and most of what was left of the charge will still be there weeks later. My only worry now is that everything from Metabo seems to shifted to their 18V & 36V tools - 12V replacement batteries / chargers are difficult to come by and they DO NOT sell direct.
