I think the narrow eyebox is the biggest issue for me, it's not bad at 1x but at 6.5x I sometimes have to readjust a few times to get it right. Not sure how other scopes compare to this one though, I have no experience with optics. This is my only and first scope aside from a cheapo 4x20 I got with an old levergun, that I promptly removed.
I read elsewhere that the biggest cause for the tight eyeboxes on scopes like these is the small front objective and it gets only worse if you increae the zoom range so I wonder how that 1.8x stacks up here. I wouldn't say no to a simple 1-6x with a larger front objective, maybe a 32mm like I've seen on certain IOR scopes, if that would give a bigger and less sensitive eyebox.
