I purchased primarily for GE's quality but also for the slide out vent. Tired of previous microwaves getting soaked with condensation from using range front burners. This slide out vent is great. Absolutely zero condensation gets to the microwave controls. The slide adds about 1 inch height to the unit but it does not get in the way. The LED lights are very bright and was surprised to see they are diodes, not bulbs. I don't know what will happen when they burn out. There is no mention of this part on GE's website. An added bonus for me is that this microwave will communicate with my new GE Profile stove, which unfortunately is on backorder.
