They are good until you look through a Nightforce. Will make you want to save and upgrade, thats what happened to me...
Whats wrong with upgrading overtime? Vortex to Nightforce to US Optics to S.B.?? Its like anything else, buy what you can afford and use until you are no longer satisfied or you can afford to upgrade. Its only human nature to want what we cannot have.
Yes Vortex is good bang for the buck but my PST FFP was not adequate for detail in the field such as judging an elk or deer at longer distances where my NF or SB is crystal clear and lets me leave my spotting scope at home vs having to lug in my pack.
