I own 2 Hammitts and I adore them. Buttery soft leather and holding up beautifully. Mine are the small Tony (black with gunmetal) and the Mini Tony (black with gold). Their others (reversible bags in particular) are awesome too, but those styles are far too big for my frame, so I never bought one.
I was thinking of getting one of their white bags from the retiring range because I've been wanting it for around a year. Still thinking but haven't decided because I really don't need another bag, lol. The sale is around for a few more days, so I have time to pull the trigger.
May I ask which style you ordered?
If the rivets are your thing (they are definitely mine) then I would recommend these bags. I find the gold hardware a bit loud for my style (although stunning, they are definitely quite shiny and there's a lot of it between the connector rings and the rivets) so I reach for the one with gunmetal rivets more often.It's edgy and subtle.
In terms of quality, they're buttery soft and really age very well. I have seen some really bad ones in suede out and about (not sure if the owners didn't care for them properly or if the suede quality is piss poor), so based on that I wouldn't try a suede bag from them.
EDIT: I remembered I have a photo of them (attached). The larger tony has rivets on the strap and a black zipper, the smaller one has a plain strap and a red zipper. They both have red lining (faux suede).
