Have the OEM rubber straps changed in the last couple of years? Mine needs replacing and I've found two that are vastly inferior to the one I have, even in its worn condition with the hole stretched. They aren't soft rubber and feel like cheap silicon. Is it just me? My original strap is darker in color, much softer, springier with one smooth continuous v shaped groove in the center of each section on the back, and has a single wide keeper. The new ones are only slightly similar in looks alone.
All that being said I have to travel to an AD. The two I've purchased were from an individual and from chrono24 online

The first one I accused the seller of sending me a replica, but the one from the retailer was identical. Now I feel bad I made such a fuss about the first one.
