I haven't returned mine. But I will say I had to order my bags sight unseen, the trunk shows ran a little late in my area and they did not even had samples of the colors I was looking forward to at the show. I do not blame people for returning if they went thru the same situation as me, too much money to be spent on something that is not wowing you away.
I had to place special orders for my bags. Basically I made my SA aware that since I had not seen the colors/bag IRL that I may return them since I was not sure what they'd look like. But so far, so good, I liked them and I did not return them.
For now I am done with the metallics. My bags are holding just fine, but I do not use them everyday. What I would like to see is more bags I can use on an everyday basis.
