I usually use Maybelline's sheer minerals foundation or age rewind. I decided to try the mousse after it went on sale. I was pleased with the color matching to my skin tone, which I was able to do with a color sampler I found in a magazine -- just enough of each shade to do a quick test on my skin before I bought a full jar.
I apply the mousse with a foam wedge. It goes on pretty well if I don't gob too much on at one time -- otherwise, it clumps up and leaves tiny chunks of makeup on my face or that fall on the counter.
Once I got the hang of application, I was overall pleased with the results. While it still doesn't cover blemishes 100 percent, it seems to provide more coverage than the liquid bases I'd used. Still not the perfect makeup, but pretty close, especially for the price.
