The green checkmark is just as good as the red NOPE-mark: Just because there is maybe a slider for a range of 70-90° doesn't help the user make a purchase decision at all!
I have no idea what Valley's FOV range is, maybe it's 50-120 horz (16:9), maybe it's 50-70° vert, maybe ... see the problem? Just saying "Yep, FOV can be changed!" is *almost* non-information.
