I didn't vote, since I'm not from the sun belt, but it's been 90-95 high temps in the last few days. I was a little skeptical, too, with an electric A/C, but ECO mode with the climate control system in AUTO and set for 76 has been plenty. Just to test it I cranked it up to max in manual mode, and it blows as cold as any vehicle I've ever owned. The kids LOVE the rear seat vents, too (didn't have them in our last car).
