Product review (4 stars): Works Great - Very Versatile - 1 Year Review
I was surprised to read so much negative regarding this product, which prompted me to write a review.  I must say that my first issue with the GR Profile Spacemaker JVM1790SK, is the dreaded exterior (stovetop) bulb.  Bulbs burn out - I get it.  And now I will find a replacement and replace it myself.  I already unscrewed the (1) screw and slid the protective plate off.  I pulled the small bulb and see that it burned out.  I'm sure the design is taking advantage of built-in obsolescence, that guarantees residual income...but that's another story.

PROS:
MICROWAVE Works and has lots of power options
CONVECTION Works and will even brown during baking and roasting options
POPCORN Button - Pops nearly to the very last kernel
COMBINATION FAST BAKE - Utilizes Convection & Microwave in intervals
VENT - 3 Speeds / 2 removable/cleanable Metal Filters (washing them now)
STOVETOP BULB - 2 Brightness Levels / Easily Replaced / Automatic On/Off You Set Times!
ROTATING TURNTABLE- Rotates during Microwave & Convection Modes - Reverses when door is opened and closed - Also Option to Turn it ON/OFF
(2) Racks!
LARGE INTERIOR
GREAT LOOK - Silver & Black

CONS:
Trays Don't Slide Out - I think this is a design flaw which is why I didn't give 5 Stars
Bulb Burned Out - LOL
When I saw this Model in Demo Mode, there were some cool blue lights that followed the dial around as you made your selections.  I was disappointed that it was strictly a demo and not a function.  Would be helpful under low light.

If anyone know where I can purchase the replacement bulb for cheap, please reply.  I am going to start my google searches now.

Enjoy!
