I will see if they are "open to the public" but their website says this:
About Reception
We test out our iPhones in all of our cases but in some areas reduced reception or spotty reception is more apparent with the brass case. If you feel like you live in an area or use your phone throughout areas with spotty reception we suggest you purchase an aluminum case. All colors and styles of aluminum prove to have consistently better reception than our brass versions. We made the brass because we love its beauty and most people won’t have any problems, though we cannot guarantee this for everyone. Our brass cases have been our biggest sellers and most customers are happy and continue to buy a second (or third) brass case, but if you are worried about this we suggest the aluminum. If you do want to try the brass, I’m sure you will LOVE it, but if it isn't’t the case for you, you are welcome to exchange it or return it with in a week or so of receiving it.
The wood cases are really beautiful, however, you people might make fun of me for this, but since I don't wear brown shoes, or anything brown for that matter I am against getting the wooden case for matching purposes...

Maybe if they had an ebony case I would get that one...
