We don't think it is very user friendly.  It is easy enough to use once you learn it, but it is not intuitive.  The button that is used for the timer, cooking time, cooking power level, etc. only allows for 15 second intervals and adds extra steps.  No quick time buttons, other than 30 second button.  On our previous GE Micro it had a number pad which is much more flexible and more user friendly.  I would not have purchased this Micro, but it came with our new house.
