I have no idea for certain, but I would guess really well. Mostly because I saw one of them for the first time ever in Seattle about 3.5 months ago. At first it was just one, then I saw another one a week later. The frequency kept increasing to the point where I see multiple ones every time I go on a short grocery trip a few miles away. They expanded to the point where they are everywhere here now, and I doubt they would continue expanding it so aggressively if it wasn't working out.
