Very happy with the Ringke. It feels so OEM and integrated. The only downside, and I have see this in other photos, is the cutout for the camera and LED on the back. It's ever so slightly (0.5 mm) off. The only other thing is that the clear window is larger on the Spiegen, whereas the black border takes up more space on the Ringke.
XDA needs a "2nd Post Wiki" automatically generated in each thread. Such a thread wiki has proven effective on other sites to cut down on useless thread clutter and questions which have been answered repeatedly. The idea is simple. A community-editable wiki is inserted immediately beneath the OP to address current issues relating to the topic. Most OP/devs don't have the time to continually update their OP to address ongoing issues. Let's let the community do that for them!
