I ordered two of the Columbia Men's 38mm Cotton Washed Webbing, Beige, 42.  I have only worn one so far and that one has been a sour experience.  It is very difficult to lock and to unlock.  When I attempt to fasten the belt, either the top or bottom of the moveable lock sticks causing a very bad bind.  After fighting it for a minuet or so, I can get the lock to straighten up and
then it will move back to the locked position.  If I am lucky it will hold, if not, I have to fiddle with it for another minuet or so to get it to hold.  This might start moving back and forth properly after awhile, but I shouldn't have to fight it every time I use it. I will give it a few more tries to be fair to the seller, but if it doesn't start locking and unlocking smoothly, I will most surely return it.  I was in the military for ten years and the same type buckle held up my uniform trousers.  I never, in all those years, had trouble with the military buckle  This buckle appears to be totally unacceptable.
