Okay, I had a problem that Nikon could not solve, having to do with the Prostaff 5 12x50 binocular (I bought from you) that has a female tripod adapter thread, but too large to accept normal L-shaped brackets. The cap was so difficult to remove I scratched it up rather badly with needle nosed pliers before resorting to small vice grip, which worked. Your agent at this point sounded not only perplexed but uncaring about the situation. He did, however, supply me with the NIBM letters to look it up with in the catalog, the one and only reason I gave 2 stars instead of 1. I hope it works, or no more business will ever be conducted with you by me. You have always been my preferred source of optics and was wishing to further my collection, if that even matters to you...
