I had problems with mine, Neverfull MM, that I purchased several years ago and my local store wasn't very willing to "replace" my bag, at all, even though there were problems with the straps cracking just after a few weeks new. After a few go-arounds, including having the straps replaced, I insisted that I still wasn't happy and was told that they were "going to make an exception" and give me a credit on the bag to get something else. Then a couple years after that my SA told me that they had made some changes to prevent the problem of the cracking, including shipping and storing the bags with the straps not tucked inside, and said that the problem shouldn't happen anymore. So I bought another one. Carried it a lot as my winter work bag over the last couple of years, and just recently started to notice some slight start of cracking where the straps tend to bend a little and move from the petals which are the leather pieces attached to the bag. Again, I carried this bag often, though. But I asked the manager of my store about replacing the straps recently, and she said, sure, and that it would cost me $260. I said, "no thanks", and have since sold it to a friend who really wanted this bag at a good deal. I have just bought the Epi Neverfull MM. These straps seem to be more supple and have more ability for movement, like the Mono Neverfull and the Azur Neverfull (I've never tried the Idylle Neverfull). That's my story!!
People love this DE Neverfull, and it is a really pretty look. I just don't think those coated straps on the DE move that well.
