To start this review I will state I was not sold on this company and the products at first, but after reading some reviews, and watching videos, people touted the glass as shooting way above its price point as well as offering a superior built product. I was at most cautiously optimistic. Soon there after I called GPO USA having some questions I wanted answered, and that soon turned into me wanting to order their products. While I was phone I had the pleasure of having a conversation with the CEO of the company Michael Jensen. He was thorough in going over all the questions I had as well as telling more about the company, warranty, and the quality they stand behind. I soon after ordered the passion hd 12.5x50 binos. All I can tell people is WOW! The clarity, color, and quality of the product I received was on the same level if not better than some of the other high end binos I have had in the past (vortex, maven, zeiss). Trust me when I say spending your hard earned dollars on a product like this makes me feel good knowing about the people, that not just operate but care about the company and what they put on the market. This leads me to my purchase of the GPOTAC 4.5-27 scope purchase. When I was having my left handed 1968 Remington 700 built I knew exactly what I wanted to put on top of it, a GPO scope. It did not disappoint, edge to edge clarity, color, crispness, and build quality is on par with what I now know and expect of GPO! The scope was very easy to zero, simple to set the zero stop, the push/pull locking turrets are a great feature, and the parallax is as smooth a butter. If anyone reads all this all the way through all I can tell you is if you have landed here looking at GPO well you are in the right place of great quality and fantastically clear glass give them a try!
