Cool case, didn't figure out what the trapezoid is Cutout is still outs are for. There are two battery compartments, but those other cutouts confuse me, maybe they're just aesthetic or structural. Oh be aware it stinks at first, I had a lot of fun with the lemon flavored sachet they include to cover it up, it doesn't work. Maybe it really is just silica gel or something. Of course, don't try to make a cup of tea out of this lol.
