I really love this watch.  I was expecting BIG, but it is a nice size and I am happy with the velcro strap and color.  The BIG problem is that it came with no instructions.  HOW DO I CHANGE THE TIME ON THIS THING, or the date, or the day, or anything.  I have tried mode and all other buttons, to no avail.  I would have given four stars, but am, at the moment, unhappy.  But, then, it just came in the mail.
UPDATE:  I called the number given for questions on the watch I was told where the directions were.  After locating them I programmed it just fine.  It does get dirty and so far the only thing that cleans the strap for me is scrubbing it with Dawn.  So, wish the strap was easier to clean.
FURTHER UPDATE:  I love this watch.  Wear it night and day.  At night I use the light feature to see what time it is if I wake up.  It is just big enough that I can see the time and date very easily.  I don't worry about it getting dirty anymore.  Just scrub the band with Dawn now and then and let it dry on the counter above the sink.
