I love this watch; the only problem I have with it is a problem I personally often have with watches -- I have a pretty skinny wrist, and even though this band is nylon & velcro, it still doesn't work for me very well.  I'm going to replace it with a plastic band I can cut to fit (like I do when I get a Casio digital watch).  The watch itself is great -- easy to read numbers and looks really cool.  One other minor issue -- the instructions only talk about how to set the time & date; there's no info about the battery.
