QL: I had similar experience with Andiamo zippers. The good news was that the dealer I bought the bag from sent it back to Andiamo and it was repaired at no charge. I also had problems with Tumi zippers, and they charged me for the repair.

Ballistic nylon on the Tumi bag went 3 1/2 years (probably 300 checked segments) before it started to show any wear. The nylon on the Andiamo bag is showing no wear and tear anfer 2 years and probably 20 checked segments.
