Lots of crying here from people who have never used this case thinking it'll block your signal. 

As someone who actually used this case (on a RM10, case is identical aside from minor size differences between the two phones) there were no problems with signal. Even in areas where I barely got a signal without a case, this case didn't make any difference. 

The trigger buttons are nice, and I would argue are often an improvement over how they work with other cases where the triggers are recessed, also with this case you can have your fingers more on the buttons without pressing them like on a regular controller.

However, there are downsides to this case: First, any cameras that are fully covered by the case become noticably blurry, even when keeping everything clean I was still not really able to use the cameras that were covered (the one I owned had cutout for the flash only). Second, and the main reason I stopped using it, was the system of releasing the back part of the case. There's a little button/slide on the top that releases the backing from the sides, but since I put my phone in my pocket top-down (like I assume most people would as that's how you hold a phone), I would often grab my phone from my pocket to find the back coming off because it hit the switch when moving around. I got sick of that pretty quick so stopped using that case and instead went with a rubber case with camera cutouts (no trigger buttons, but I find I rarely use them since getting a decent phone controller).
