This Gallery combo was a replacement for the Frigidaire non Gallery version from 2008 (old one lasted 14 years w/ 2 oven repairs before the microwave died). The new Gallery is a little more low profile meaning it doesn’t stick out from the cabinets as much once installed. Looks great. Install was ok (this has a short cord - so pay close attention to the spec sheet when doing the electric. Electric is top left versus the old one down at the bottom). 
The microwave is QUIET and powerful. Huge improvement from the old non Gallery version. Oven preheats relatively quickly. There is no internet connection/smart function - not a big deal for us. It does have some functions we are excited to try (e.g. air fry).
Overall happy w/ it. Time will tell on the durability.
