Very versatile but the handle is short for a comfortable grip. I like the extension, but I'll still go with the Mars because of the clutch. Edit: Although I have Mars and Kings County Tools (blue) at home, I'm buying one of these to keep in my class. KCT (blue) is a few bucks more and Mars only has 2 hex/hex bits - a lot of desks and things I need to set up at school have a hex/hex key and there are 3 of these sizes.
