I wouldn't have expected the deterioration displayed on that watch, based the stated use. I'd also expect a manufacturer to offer to review the item and determine if it was down to a manufacturing/curing fault. For £200 I'd be annoyed in the same position - even my heavily used Hirsch pure straps look considerably better.
A number of people have said they have one and it is fine - but what has been the real world use? I have a Rubber B myself, but to be fair I have possibly worn it 3 times maximum in the years I've owned it - it looks better than the OP's one though ;)
As for Rolex - I believe Everest Bands are or were OEM supplier to both Rolex and Tudor.
