I got a mia about a week ago, and while it may be too soon to have a definitive opinion on it, I love it so far. I don't really have problem skin but do typically have little bumps on my nose and a bit onto my cheeks (clogged pores I'm guessing?) and those seem to be going away. Also, my skin just looks a lot more even-toned and feel so smooth. I have very sensitive, dry skin and the sensitive brush that came with it has been fine for me, though I usually just use it once a day. It was a mistake to use this on an area of my skin where I had an eczema flareup though because it just made it even more irritated. So far I'm very happy with my purchase though!
