This trim kit is an injection molded plastic frame with a very thin stainless stamping adhered to the front only (not the sides) of the plastic frame. The choices are slim, so I settled. My last GE Profile trim kit was solid metal and heavy. This one weighs nothing and is still expensive. I guess GE keeps the profit. The sides of this trim kit is cut away (presumably for venting) so you can see inside and see the plastic ribs on the core side of the plastic frame, which looks cheap. My main message to GE is that the diminishing quality IS NOTICED by your customers. A high quality budget part does not look the same as a high quality nice part. To buyers, please be VERY careful you order the exact correct trim kit for your microwave. GE constantly changes the numbers and randomly discontinues items, and they seem unable to design new microwaves that use older trim kits. Part number matching is critical.
