My SM3's case (one of those curvy silver ones) was damaged in shipping. One of the side panels is coming unglued. The case is really only useful as a dust cover at this point. The major damage seems to be the glue failing, so I'm going to attempt a repair if I can figure out how to clamp it.
But even if I do repair it, I'm not sure I'll ever really trust it. I'm finding that it's easier to find the SM7/8/9 case (the two-tone one) than an SM3 case. Is the mounting hardware on the SM7 case compatible with the SM3 body?
I've occasionally seen on SGW or ebay an SM3 or SM4 in the two-tone SM7 case, but I'm not sure if those are original cases, or just something that was "close enough".
