I swapped my over the stove GE microwave with the GE Range Hood (JVX5300SJSS). The box said it only takes 10 minutes to install- more like 3 hours with the help of a second person (my wife). The item does not come with a power supply; you'll need to purchase one separately. But after getting the necessary extra parts and lining up the vent, the hood does it's job fantastically!! It's also very easy to clean. My suggestion for anybody looking to replace or add this appliance to their kitchen check all the prep work you have to do before taking on this task. Now off to installing a backsplash....
