Purchased in February 2015, I have only to use it now. To my surprise the drill vibrates low and high speed very unpleasant manner; the vibration is found at the end of wick and gene work in precision drilling. The problem obviously is that the axis of the mandrel is being twisted slightly eccentric: the blow mandrel is not running "round". I do not know if it's a fault general construction or a lack of quality control, but it gives me a fatal flaw. As already mentioned, the integrated lighting does not illuminate the work area at the end of the bit or screwdriver bit! I expected better quality from Black and Decker. Purchased promotion on Amazon, I hope it is not part of a lot downgraded ...
