I have four and my dad has three or so. It's what I use, period. I have other brands and variables but when all is said and done the VX I, Vari-X II is what I end up looking through. As far as I can tell they are the same thing and I have yet to have one fail. My dad put one on a high power air rifle and that supposedly screwed it up do to the recoil on the air rifle???? I guess the piston on an air rifles recoils the opposite way and screws with scopes designed for rifles. That was the only mishap in 40+ years and I haven't been all that nice to them. Some have been beaten harder than others depending on what rifle they are on but none have disappointed. I'm not sure if you can get target turrets installed on them but that isn't all that important to me as all my shots are 300 yards and under. At that distance turrets are a waste of time IMO.
