Korth does really well. Love their customer service. BUT I just got burned with buying a second hand Leupold at auction. Paid over $500 for a "New in-box VXIII 1.5-5x", somewhat high $ but they aren't made any more and it was just what i needed on a particular rifle. Got the "new in box" scope, and adjustments were not smooth. Sent it to Korth. Korth said it was a fake. To their credit, they sent it back to me at their expense, but of course not fixed either. I was aware that there were Leupold knock offs in 3-9x and some of the fancier high power models, but unaware that there were counterfeit Leupolds in the low power variable style too. I sold that scope for $25 get rid of it. That's all anyone would pay for a rough, kinda OK new fake. That was an expensive lesson.
