I was impressed by how much smaller it is than my previous 13 year old Makita that was stolen. I've been a fan of Makita since they invented the cordless drill and cordless tool in the early 90's. This brushless drill is very quiet and you will not see any arcing or sparks in the armature as it is brushless. I can only assume they improved the bearings to keep them that quiet and according to the Makita website, omitting the brushes can increase performance by 50%. I need to see THAT, but now this little guy is striking!
