Milwaukee #1 or #2 ECX Bit Size

[mod600]

I'm looking at the Milwaukee ECX screwdrivers. They have a #1 and a #2. I'm assuming the #1 is smaller and probably sized for the screws on outlets and switches and a #2 is larger, and size for the screws on breakers and screws in a service panel. Am I right in my assumption? I have not seen these in town, so I can't check the physical size, so I'll have to order them online and just wanted to order the right sized one.
Thanks!

The #1 ECX fits screws that a #1 Robertson (square drive) will fit in the center. The #2 ECX fits screws that a #2 Robertson will fit in the center.

That doesn't answer my question...I don't have the Robertson bits either...

Buy both and be prepared. Or don't get either and use a phillips.
