I have been procrastinating getting a cordless drill/driver for a while, this time around that is. It is one of these tools that you can always borrow from friends or the office, a tool that mostly just sits there not getting much use at all. The Doh' moment comes when you really need a screwdriver there and then, but cannot get your hands on one.
Of course once I got this item I wanted to have a quick look inside. When I opened it I found a 18650 battery inside just as expected -- I shall savour it for a future mod.
