This is a very user friendly microwave.  If you only use the microwave 
function, I am sure you'd be happy with it.  But it's also a handy 
little oven.  I have made pizzas, cookies, and even a pork loin roast in
 it!  I cooked the pork loin using the combo cooking function (microwave
 plus convection) just to test it out.  The results were very good; a 
nice moist roast. A 14-in round pizza pan or stone fits in it and also 
(just barely!) a 9x13 baking dish.  And yes, you CAN put metal pans in 
it when in oven mode.  When we first got it we set it up on the counter 
in our main kitchen for a couple weeks and played around with it.  Then 
we moved it to our newly renovated "bar" in the basement which 
truthfully is a small, very functional kitchen.  This oven is a great 
solution as we can use it for popcorn, etc. in microwave mode, but also 
bake pizzas.  Another idea I haven't actually done yet is to use it to 
bake or warm a casserole for a big holiday dinner when my main oven is 
busy cooking a turkey or something.  In fact I like this oven so much 
I've decided that when we renovate the main kitchen I am NOT going to 
opt for the double wall ovens but instead get a regular range plus 
another one of these and then I will have 2 ovens plus a microwave, 
basically!  I think it's a wise investment and a very excellent product.
I purchased and installed this microwave for a family member.  We looked
 all over for a high quality built-in (above the oven, aka cabinet 
mount) convection microwave.  The GE Profile and Advantium lines were 
very poorly rated online and did have a very good repair history.  It's 
tough if you want a large microwave (capable of spinning a 9x13 dish) 
that is convection and has a good repair rating.  After seeing that the 
selection available in the marketplace is poor (We looked at Sears, Best
 Buy, Home Depot, Lowes, and at a "Factory Direct Appliance" store).  
All basically sold very few cabinet mount microwave and those that they 
did have were either a.) small and very cheap or b.) GE Advantium and 
very expensive ($1200).  Since the Advantium has a very low customer 
rating all over the web, we decided it wasn't worth the money.
After
 reading online we noticed that approval ratings of Panasonic Microwaves
 were very high.  They use a different style of microwave element that 
they call an inverter.  This means that, when using lower power levels, 
the microwave doesn't turn on and off the element.  For example power 
level 5 on almost every microwave means the element turns on for 2 
seconds, then off for 2, then on again.  This means that delicate foods 
come out screaming hot in places and cold in others.  The Panasonic has a
 proprietary element that actually has adjustable amounts of power it 
can output.  This is something that sounds like marketing but in this 
case it is truly unique and directly beneficial to the customer.
The
 "sensor" cook option works really well.  We followed the directions to 
bake a potato.  The microwave instructs you what to do on the display.  
The result was a large perfectly well baked potato in about 90 seconds 
all managed by the sensor.  I was shocked at how well it worked and how 
fast it was.
Be purchased the mount kit (the unit is for 
countertop use out of the box).  The kit, while expensive, is very high 
quality and well designed. It was easy to install and looks great.  It 
matches the Samsung fridge perfectly and is neither cheap looking nor 
"showy".  It, like the microwave, is very austere and modern looking 
without being too "high tech" looking.
I'm VERY pleased about 
this microwave and think that its a good value for its price.  It comes 
with racks and ceramic turn table.  The interior is all stainless steel.
  Overall I can't find a place that Panasonic cut a corner in the 
microwave, accessories, or the trim kit.  For the price (less than half 
the price of an Advantium) the build quality is perfect.
