I do think the bag is a little dated. But that doesn't matter if you like it.
I actually have owned the mini pebbled leather Hamilton crossbody (8" x 6") for about 6-7 years now. It's one of the last contemporary bags I've kept as I've moved my collection to premier.
I kept it because it's a cute bag and it's incredibly durable. I've really abused the poor thing (it's my go to for busy / messy / can't baby a bag situations) and the leather still looks great. The tiny bar holding the medallion fell off a year or so go. So I just super glued it (with the medallion) back on the bag. So, overall, I'd have to say the quality has been great. The construction and leather is what matters to me and that's what's held up. Gluing on the little metal piece was no biggie.
So, if you need a satchel, like the look of the bag and aren't worried about weight, go for it.
