My latest UV (June 22) has a different rubber material from those produced earlier. It looks the same but has significantly more 'stiction', which I think is an improvement in use. Not sure if the new rubber will be as good as the old rubber in 15+ years.
Leica has the most durable design of them all, including old Trinovids. They just keep going and going. An example the rest should follow.
Swarovski needs to fix its armor issues or it will lose credibility, it's already on the edge with its self-destructing armor.
