I bought these pants for a friend who could not use them.  The nice folks at Amazon allowed me to exchange them which I did.  I could have opted for a refund.  I am specifically writing this review about the Amazon Locker used for the replacement.  I really like Amazon lockers.  There is one 1/2 a block from my apartment, convenient.  But here's the thing.  When it was first installed, the locker had a touch screen used to enter your code to open the box.  Problem was you could not, I mean absolutely could not, see the touch screen in the daylight, and therefore had to wait until dark to make your return.  Well Amazon fixed that, at least on mine, by installing a 'numerical' keypad on the box. Note it is numerical, not alpha-numerical.  The keypad works great when Amazon gives you an open code that is all numbers.  But, and I can see you are thinking ahead of my writing, Amazon sent me an alpha-numerical code for this return, making the keypad unusable and forcing the use of the barcode scanner.  Try navigating your box in front of one of those sometime.  You can do it but you won't get it on the first try I'm betting.  I thought the scanner wasn't working at first, then, the box opened.  Hello Amazonians, your software wizards are some of, if not the, best in the world.  How about instructing the wiz kids to only give numerical codes to those of your faithful many who chose return via Amazon Lockers?  Thanks for listening.
