I love the express cook feature on the microwave. You hit the 1 and it cooks for a minute; hit the 2 and it’s 2 minutes. I haven’t looked at the manual to figure out how to put in a set time (like for popcorn).
Popcorn button is not used (as most popcorn manufacturers will say on their bag “Do not use Popcorn setting”. U tried it once and it didn’t work. I went back to just putting in the time.
Overall the times needed are consistent with what is listed on the item. We haven’t run into any cold spots when heating food.
