I saw them at a JBF sale, and I thought the "diaper" bag was too small. Ditto the pp it is just their large bag. That would not have been big enough for me.
Are you planning on going back to work? If so a diaper bag that is also your purse may not work for you....since you'll still need a purse to take with you to work. So while it seems good in theory, I think it may not work as well as it appears.
