I've been using my GST off and on since September. I have traveled with it twice -- heavy, bulky stuff. The chains and links are fine. I see little separations in the links themselves, but they have to be there because that's how the chain is manufactured. The leather in the straps shows some little bits of thread, but again, that's to be expected after wear. There's nothing about the chain that bothers me. If a link actually broke or the leather tore in the handle, then I would take it back to Chanel.
If the chains are handmade then of course you would see some inconsistency. With all the stuff I put in there, it would have killed any lesser bag!!
