This is a a very nice tool. It is plenty powerful, but at first I was a little disappointed because it is still not super light. (4.2lbs) The Griots rotary unit is lighter but not as powerful. I do wish it had a trigger instead of a switch on the side. If i had to make the choice again, I would probably buy the Griots G13 which weighs 3.15 pounds and has a trigger style switch. The Flex build quality is excellent, and I enjoy working with it.

This is a great addition to my larger Flex unit.. Great quality!!
