yeah when it comes to tools...if you plug it in...you have power. If you snap in a battery? meh. I have never been happy with ANY battery powered tool, from a simple sander thru a drill thru a weed wacker. Plug it in...you'll be done quicker. This applies to everything except certain tools that I know certain ladies here immediately thought of when I said the word "tool".

My husband prefers my Dremel...a heavy duty one from Home Depot for drilling hole to the cordless drill.
