Product review (1 stars): keep on looking
I purchased this over the range convection microwave/warming oven when I remodeled my kitchen and was excited to save countertop space, have a microwave and convection oven/warming drawer all in one.  I was wrong.

  The controls are not easy to manipulate, and when you are baking with the oven, it keeps beeping.  That gets very annoying.  The logic with setting time and temp, power level and functions is extremely flawed.

  Secondly, the microwave is definitely sub-par.  For such an allegedly powerful unit, the microwave is rated at 1100 watts.  Kind of pathetic.  No, it IS pathetic, especially when el cheapo models from warehouse merchandisers have ratings of 1200+ watts that are much more user friendly.

  Third, the "range hood" is absolutely and completely worthless.  It is loud and does an absolutely HORRIBLE job at exhausting cooking vapors.  Even on "high" it cannot remove the vapor from a single boiling pot of water.  Furthermore, even after some modifications, the front of my microwave is covered in grease from the rising vapors the hood doesn't catch.

  Seriously, don't waste your time or money with this thing.  After 2 years I am ready to rip it off the wall and smash it to bits, that's how much I hate this thing.  Unfortunately I am not made of money so the only option that leaves is to build an extension "hood" that juts out 6 to 8 inches with 2 inch wide banding curtains so that the hood actually captures vapors and smoke.  I pretty much regret buying this thing in the first place, and discovered that within the first week I used it.

  I don't know what the answer is for a combo micro/convection/warming drawer, but this unit most definitely is not worth the box it comes in.

  Hope that helps.
