I've got one of those linked from buy.com (got it on ebay), and the phone sites perfectly upright, no angle at all (and sometimes has a tendency to pitch slightly forward. If you have any case, it'll not fit on that one either. I've since hacked the slot for the phone up with a dremel, and have it widened enough for my Casemate case (which just got replaced with a Otterbox Defender, so out comes the dremel again, lol). The one I have doesn't flash the leds, but they DO stay on. If it's in a room where light is a problem, you'll need to either cover the lights, or darken them somehow (sharpie?). Wasn't a problem for me as it's on my desk in my office. The external battery charger does appear to work pretty well, and it will keep the phone charged at the same time, but the build quality on both the case, and the actual electronics inside are pretty low (the board is attached to the inside of the case with what looks like hot glue, and kind of hap-hazardly placed in the box.
It works, but not without some modification.
