Update: Vapor Pro Spectra: Nice!
I have had my Vapor Pro Spectra for about a week, so just wanted to share a couple comments. Nothing earth-shaking, just an observation or two.
Design: Based on some of the great photos on this thread, I went Silver/Silver, and it looks just amazing on the black iPhone. I have a few other cases, along with another aluminum or two, and this is the one I am using on a day-to-day basis. Super feel and impression of quality.
3G/WiFi: As others have measured, I did not see an affect.
GPS: Unfortunately, this can be off at any given time. Not so much lock speed, which is very fast, but actual location, which can be right on or off about a 1/2 block. [off topic: hoping for a report from one of you on the GPS with the E13ctron hybrid back]
Accessories: Just a couple surprises for me, both positive! For dusty environments, I REALLY like the zipper case that I purchased with it. Just what I was looking for. Also, it came with this microfiber back cover. I thought I was just going to throw this, but then I decided to just give it a try. I am really surprised, but I like this!
Anyway, a positive feeling about this. When I travel and need GPS the Magpul or my M-Tech carbon come out, but for most of my use the Vapor Pro Spectra is just great.
