FOTOMIX Camera Quick Release L-Plate for Nikon D850 Bracket Holder Vertical Shoot Hand Grip Mental CNC

The vertical side of the plate stands off the camera nearly 1/2". Not well executed.

It doesn't sit perpendicular to the axis of the lens. As I tighten it down, the plate twists itself counterclockwise noticeably. It isn't that it is loose -- the plate locks down snug, but misaligned. The net result is that the camera lens is pointing slightly left of perpendicular to the clamp. Enough that if you level the camera using the virtual horizon with the clamp in landscape orientation, and then flip to portrait orientation, the lens will be pointing downward, so you'd have to re-level the camera again. Closer inspection shows the hole for the 1/4-20 screw that secures the plate to the camera is misaligned.
