For procedures and instruments it works great. For primary flying and landing it is pretty useless. Nothing against redbird but all of these types of simulators won't let you feel the actual plane flying. You don't get that increase in G's as you flare, the feeling of your butt sliding to the side when you are not coordinated in a turn, the acceleration/deceleration you feel as you try to land in a gusting wind, etc. If you want to go practice approaches they are much cheaper than actually flying them and can be re-set without having to take off again. They just don't do much for actual piloting skills.
