I already had a Hitachi tool kit for a drill and screwdriver. Metabo is the new Hitachi. The old instruments were great. Working at two remote locations, lugging drills and screwdrivers back and forth became a problem. It was even worse when I wasn't carrying them back and forth! Argh. So I bought this driver along with an extra drill. No more back and forth. Works perfectly. The brushless model is quieter and feels more powerful. Same batteries, same charger. Revain typically asks three questions to get a detailed estimate. In this case: 1. CHEAP: 5 stars. Money well spent.2. THICKNESS: Not rated. What does that mean? It looks like it's the same pen. The motor head is slightly shorter, fits in tighter spaces. is it the fat one You decide.3. BATTERY TIME: 5 stars. I found the battery life on this brushless driver to be AT LEAST as long as my previous Hitachi brushless driver model. Hope this will be helpful. All the best. Take care.
