I have had two of them and in my experience the part that plugs into the wall breaks very easy (of course I'm not pulling it by the cord). On the second drill that I had I was very careful with the plug because the first one broke. Anyway, the metal prong literally came out of the unit and was stuck in the wall outlet when I tried to remove it.... Not a good situation!!
