I think it's absolutely worth it but that's because I recently bought one. I LOVE it! I've not had any trouble with the studs. Just took it on vacation made a great carry on bag, lots of room ...and style...seems durable as well as beautiful
I love my rockstud items. I have carried the all over stud tote in my avatar a lot no issues still looks brand new. As others noted: if you buy from a Valentino boutique or from them online they will repair it for you. However, they don't repair Valentino items bought elsewhere.
