I just bought the medium quilted bay in black, and I am not sure if I should keep it. After examining the bag, the leather on the quilted part seems so-so, and the zippers are not very easy to use. For those who have have this bag, did you guys think it was worth the money? Also, how's the bag holding up? I am a little worried that the leather may not very durable. I'm looking for a versatile, long lasting, everyday black bag. If the bay bag doesn't work out, do you guys have any other suggestions?
