I have been using a Flight Deck since April. The greatest benefit of this computer for me is that it tells what that I'm in for both the large and small chainrings. It also gives a gear ratio. I like that I can work the controls with the buttons near my shifter.

Drawbacks: time of day is displayed in military time; sometimes you can accidently reset the computer by pressing the buttons near the shifter (I have done this while clutching my handlebars during a fast downhill descent); may interfer with a HRM; more expensive than other computers.
