I do like the bag, but that said, I bought it with a larger one, and both of them had the same strong, acrid chemical smell that initially irritated my eyes and nose.  I've hung them out to air on my porch for about 4 days now, and I can still smell it when I come out the door.  All in all, I like the quality and stitching, but I agree with some other reviewers that the shoulder strap is a little skimpy.  The strap looks more like vinyl than leather to me, and the clips are cheap, too, like the whole thing was an afterthought.

The pockets are roomy and lined with nylon, but I think that long, U-shaped zipper opening on the top is a little "cutesy" with its tiny leather strap connecting the two zipper tabs.  A straightforward single zipper would have sufficed, and wouldn't have necessitated a useless velcro flap on the one end; when it's open the long flap is in the way, and so is the velcro closure on the other end.  Also, the velcro tabs are sewn perpendicular to each other, so they don't get full contact: one side goes cross-ways on the bag, the other length-ways.  What's up with that?  (Somebody skimped on the design phase.)

And it's not 18 inches.  The big inside compartment of mine measures just about 12.5" long by 7.5" wide by 8" high.  End pockets add about 2" each, so overall it's just about 16" long.  It's a comfortable size, though, so I don't fault it for that.

Were it not for the aforementioned drawbacks, I'd have given it 5 stars.  I guess I'll try some leather treatment on it, but I'm going to give it another few days to air out before bringing it into the house.
