It looks professional without being overly professional, e.g., leather.
It travels well: it’s durable (with the below exception) and just small enough without being too small.
It’s got lots of pockets and doo-dads, like the magnet closing “stash pocket” which I use all the time and the hidden zipper on the back that opens up so you can slide the bag on the handle of your wheely-enabled luggage.
Tragically, the little clasp things on the strap broke a few months ago — one after the other. So I’ve been using it with the strap at it’s maximal length for a month or so, which is quick annoying for all the walking around I do when on the road.
So, I called up their customer service to see about ordering a new strap. After about 20 seconds I got a live person (at 2PM CST), explained the problem, gave them my address, and now they’re shipping a new strap, free of charge and covered by warranty. She didn’t even (as far as I know) look up any account info. Just ship the man a new strap!
Man, that just makes my afternoon: consumerism working ;>
