Watch was nice and seemed to be a good value.  I returned it for 2 reasons. 1) This was the primary reason (for me) - the watch face and hands were a bit small for my vision and there was no way to tell time in the dark - no illumination nor luminous marking.  2) The watch band is a bit difficult to adjust - you either have to pay someone to do it (which can cost a significant percentage of the cost of the watch) or do it yourself.  It's reasonably apparent how to do it, but I wanted to be sure of the approach and contacted Casio.  To get instructions from them on how to do it, you have to send a release to Casio freeing them of any liability if you screw it up.  There were a couple of videos on YouTube, but I didn't find them to be especially helpful.  By the way, to do the adjustment yourself, you should probably have something like a small ("skinny")center punch and a small pair of needle nose pliers.  With those tools, it wasn't especially difficult.
