You think it compares well with the PC EyeGo from Tobii?

Does it come with software to control mouse clicks, scrolling, pausing eye control for reading, keyboard?  Is this software included or extra. Do you like the software?  With so many eye trackers on the market now, I find the software interface often make the difference for many clients.  Are people able to select between blink, dwell and switch?  Thanks!
