Had my 8.5 x 42 EL's for about 16 years. Last spring I knock them off my highseat and broke the bayonet part of the ocular but because I use (and abuse) them so much it was not until 3 weeks ago I sent them off for repair.
They were returned to me today with nothing to pay. Apart from the repair above they also gave the binos a complete service - I swear that the glass is different also replaced various internal bits according to the job list.
We all know that Swarovski binoculars are very expensive but when you get this sort of backup if things go wrong, it is no wonder people are prepared to dig deeper into their pockets to buy quality and this type of backup.
