Hi everyone, I've collected binoculars over the years but never really got into specs, brands, and understanding/developing my preferences until recently. Some of the lower ends I've bought second hand came with problems, particularly a carson (cracked lens) and opticron (hair inside). Not worried about my bushnells, they seem to be no questions asked. I wish I'd read more into their warranties before buying them, because I am now learning that many manufacturers won't honor them without product registration. So my question is this, do most manufacturers require this kind of registration? Are the implied costs behind servicing/replacing that prohibitive? I mean I get it, standing behind products you made maybe decades ago can't be cheap, but shouldn't all manufacturers be motivated to do so? Greater warranties almost guarantee greater resale value, loyalty and prestige (assuming you're putting out quality product firstly) But I'm making these assumptions based on other hobbies that I have a better understanding of (knives / flashlights).
