I purchased one of these cases directly from the company about 2 years ago, and have used it daily ever since. I am hard on briefcases, often over-filling them, but this one has withstood everything. I travel internationally as well as in the USA - this bag has been around the world with me, and often generates appreciative comments.
When I originally bought it, I had been looking for a solid bag that had the older, academic look of the flapover briefcase. Every other case that that I found had snaps, clips, or other hardware that would have broken within a year under my usage. This case has real hardware that will last and has lasted. Picking a color was hard, but I finally settled on the Chestnut, and haven't regretted it.
This case has full-grain leather, with rivets, and belt-type buckles. When I had problems with one of the buckles on my case I contacted Saddleback Leather and they replaced the buckle and strap for free. I wasn't absolutely sure that it wasn't my fault, rather than a material failure. But they stood behind their product without questioning.
The handle is large, and comfortable. I use the D-rings to clip things to (USB drives, keys, etc)and then let them drape inside the bag, beneath the flap. I also have a black nylon strap (actually, a nylon collar for a dog!) that goes through the circular ring on top, which I use to attach the briefcase to my roller bag when I fly.
I've found this briefcase to be flexible, durable, good looking, and reliable. This briefcase it one of only a handful of items that I have ever purchased which is actually better than advertised. I would definitely recommend it - and would buy again. In fact, I may actually buy a second one at some point...I have two children but only one briefcase right now, and I wouldn't want to cause a fight in 40 years or so. ;)
