    There is not a trim kit available for GCST09U1WSS because it doesn't have the capability to be built-in. This model was designed for the countertop only. -Don@GEAppliances

          Class takes a front row in the kitchen
          [This review was collected as part of a promotion.] Fantastic appliance that is suitable for a medium sized kitchen. Looks amazing on the countertop and is very functional. The tech is convenient and overall very happy with the oven

            For the money, this is a great microwave.
            [This review was collected as part of a promotion.] We both like the capacity, because a kitchen has a smaller insert for microwaves. The controls are very well laid out, and it is really nice to have a design that fits with our kitchen. Since we’re new to the product performance seems to be a high standard. The power settings are easy to maintain and change. I would say I highly recommend this product.

              Fairly compact
              Nice and small I have limited counter space. Does the job well for a small microwave

                Just over 2 years old and dead
                Just over 2 years old and started shorting out after 4 seconds. Scared the cr@p out of me. In the beginning, it would inexplicably beep every day at 9:14 a.m. SO WEIRD. Then lately it started beeping whenever with nothing in it. And now it's junk. WAY TOO MUCH MONEY for something to only last 2 years. We're past warranty. I'll never buy GE again.

                We want to get more information from you about your microwave and will be reaching out via email soon. Please contact us back when you are able.
                  The delivery was after 10pm and just left right in front of our door. There were hiding places to leave the package. The GE microwave is great! It's small with a lot of power. Everything fits inside really good

                  Be aware of the child lock feature
                  Please, please, please turn off the child lock default setting . It is so utterly unnecessary and frustrating, I nearly returned the microwave due to this utterly annoying feature.
