Excellent!

Fantastic, easy-to-use diagnostic tool for Logitech Dual Action. Shows pressure sensitivity of joysticks and even tells me what buttons 0-11 correspond to. For example, buttons labeled A-B-X-Y on the controller do not correspond with the Macs interpretation of their function, so it was great to have a guide for that. $1 well spent!!
