This review is specifically about Tumi Warranty repair.
Mark's is a preferred repair service for Tumi. I recently sent a Tumi bag from Seattle for repair. This briefcase was sold to me as having a lifetime warranty.
A side zipper failed, one that is used a lot, and Mark's determined it failed due to "damage". Not only was this completely untrue, but self-serving for both Marks (they priced the repair at $60) and Tumi (who don't honor original warranties).
Mark's may be great at luggage repair but serving Tumi like this is not in their customers' best interest, IMO.
