I have the Monarch for my 7plus and while the rattling screws and the slightly loose fit at the volume controls is annoying, it's still an overall quality case.
I am a little perturbed that I have to deal with 2 fitment issues on a 60 dollar case, but they don't affect the case's ability to protect and it still feels great so I'm going to just roll with it. Too difficult to come by slim and light durability.
That said, the elago glide case my wife has on her 7+ is pretty impressive for 10 bucs. Makes me feel a little like a boob but I still prefer the Monarch and a tempered glass for my uses.
I'll just have to get used to the rattling. It's like riding around in your friends civic listening to his crappy system in high school all over again! Oh the nolstalgia.
