I received my iPhone5Mod iPhone 5 dock as well... it works perfectly so far. I received the new design that allows for vertical sync/dock and resting horizontally in the secondary cutout. It's a great design - very nice.
I also got the illumincated cable. It works great either alone or connected to the dock. It's fun to watch the traveling lights in the cable, but it's just a gimmick that will probably soon get old. I haven't seen the direction of the traveling lights reverse. The lights show travel to the dock when connected, or steady on (for a few seconds) when the cable is unplugged.
The lightning port (on both the cable and the dock) is every-so-slightly tighter fit than Apple's lightning cable. The USB end of the cable is bulky - much more so than a standard USB cable.
Overall - I'm very happy with the iPhone5Mod dock and illuminated cable.
