I have 2 Vortex HSTs and they are fine for my purposes. They track well and the turrets are well made with distinctive "clicks" and repeatable zero. What they lack is clarity in low light but for the price I can't complain...
I agree with this but add that low light performance is more than adequate unless you crank the magnification up in low light. There's an illuminated version for sale either on this site or on AS.
I have a VX6...great glass and nice turrets.
I will be adding a Meopta Optika6 for my son's gun. I have a set of Meopta binos and they are great glass for the money.
