What I can tell you is that while it's a lot less intrusive than it appears in the product photos, I had a **** of a time getting VG to actually ship me mine. I ordered it on Apr. 29. They said it had a two week lead time. 3 weeks later, I get no shipping confirmation. I reply to the sales email I received with my order confirmation. No response. I contact them directly the following week, (via email, they have no phone number, and we're now at 1 month waiting). 3 days later I get a reply back saying they lost my order. (They later clarified in a second email after I pressed them that I haven't received anything, but they definitely charged my card). Their second reply the following day said that the order showed as shipped, but they didn't have a tracking number and they'd make me a new one and send it ASAP. Another week goes by, (5.5 weeks total), and when it arrives, the 3M tape on the bottom is torn, the protective strip is missing on a quarter of it, and half of it is stuck to the bubble wrap.
Deeply disappointed considering I loved my one I got from them for my '12. At least the paint looks great.
Thankfully I had some 3M tape sheets from a different project, and I was able to create a new 'gasket' around it. The reception on it is fantastic, though. I haven't lost any signal quality at all from XM or GPS.
