I have mountune and I hate it so much it's been sitting in my car for a month. Terrible coating on it...you absolutely have to get it painted. Looks like a kid ran down the street dragging it all the way to the post office. Someone had said it matches the plastics...it doesn't. It's the only upgrade I regret.
The upside is it's a really solid piece and if you planned on painting it anyways it's very structurally sound and will last a good long time without warping or anything. I was doing some other work that required me to have the front off the car but I couldn't do the installation for lack of a riv-nut gun. I'll finally get around to installing it one day but my sole motivation for doing it is to get it out of my car.
