I notice a little more bass! I might be tripping though, I have subwoofers. Fits perfect on my 2007 xterra. Looks great. Hard metal. Screws in tight. Love it.

I get hormonal acne and this is by far the only thing that helps keep my skin tame. Yeah, nothing works perfectly but this is nearly perfect. I've been using it for 4-5 years now and every time I try to switch to something else (usually because AcneFree is sometimes impossible to find) I regret it. I was using ProActive before and it worked ok but it's ridiculously expensive (maybe they should stop spending money on their celebrity ads), Aveeno and Neutragena work alright too but AcneFree products just work better.
