Hmm... It's about as big as my 6-slot autoloader with its mini bits (which offers more torque and faster bit switching), which I have to say I'm shocked that this is a pen screwdriver using full size bits. May be for some but not for me, but if I could solicit my opinion I would like to see a mini bit version, especially if it could also be an autoloader. My plastic Triplett one is still hanging in there and goes everywhere with me, but I'd love to buy an aluminum one that I feel could last my lifetime.
