Seems to be used by a lot of CO's.  I needed a clear bag to carry all my junk for shift; and has to be clear to go through screening when entering the building.  Love it, holds lots of stuff.  Received it really quick too.  Seems pretty durable, just hope the zipper holds up with all the junk I shove in it.  Price was good too, think I paid 8.89 for it with free shipping.  I had been anticipating it to be around 20. + because I wasn't able to find it anywhere in a bricks/mortar store.  Very happy all around with the purchase.
