Excellent glass, stiff focus knob, poor fit & finish - Leupold BX-3 Mojave Pro Guide HD Binoculars 8x42mm 120904

I bought these to replace my old Nikon Monarch 3 8x42 binoculars. Upon receiving them, I was very impressed with the optical quality. The optics were much much better than the Monarch 3. I looked at a bird in my backyard it was impressed with the clear, crisp image. As I used the binoculars right after receiving them, I began to notice how stiff the focus tension is. It took quite a bit of effort to turn the focus knob, which makes fine focus adjustments difficult. I have now read that some Leupold binoculars have this issue, which is considered a quality control problem. Also, the locking diopter is made of plastic and feels flimsy. I get the idea the diopter adjustment would break at some point. Because of the stiff focus knob, I promptly returned the Mojave. I am undecided if I should order a replacement pair in hopes that it has a smooth focus and not a stiff one.
