I;m still learning about all the features but the manual that accompanies this GE Profile is well written. The controls are intuitive and easy to comprehend and use. I like to use the microwave entering all the controls manually (time,power level,and start). I've had the unit for only 3 weeks and I must admit I come close to choosing wisely. I've not yet tried the convection baking but will do so next week when some out of state family members will be visiting. I like the setting choice for automatic time conversion from conventional to convection baking. Finally, it's enjoyable to investigate each in the long list of features.
