After having a pair of SLC's for 11 years and being dragged around, direct rain, snow, dirt, ect. Airline flights this and that, they were still performing great. About a month ago I called Swarovski and talked to a friendly rep. then I box them up and sent them in for cleaning and inspection. They returned at two weeks with a courtesy call that they were inbound. Upon receipt, was a packing slip stating inspection & external cleaning, replacement of all armour, internal cleaning, alignment, replacement of eye cups, repair focus mechanism, and replacement of prism/housing. Stamped Closed and no charge! That's part of why I went with Swarovski 11 years ago legendary customer service.
