First I have heard of Vortex having issues. But I had problems with one on a CZVarminter . Sent it back and Just got it returned. I have a Vortex on the cz now. Wanted more power with the new scope. Haven't had a chance to try it. But the old scope is deadly accurate. The other Vortexs I have are all good scopes. I do have a couple Burris scopes, but will never purchase another. When I get this back on a rifle, I will try and remember to tell the fire how it does.
