I bought this to wear when I'm doing things that might ruin (or kill the battery) on my $250+ smart watch.  I've worn this $16 Casio instead of that expensive watch every day since it arrived.  It looks great, albeit a tad bit smaller than I prefer.  I expect that I'll own one of these for the rest of my life, even if I have to replace it every few years.  The day name could not be set normally when the watch first arrived.  I "fixed" this by manually advancing the day by spinning the hands around a couple days.  After doing that once, the day can now be set the normal way.  Something must have been sticking from the factory.  Outside of that small, temporary, and easily remedied problem-  it has worked flawlessly for the week that I've had it.  I'll update if anything changes.  CONS: At this price point, I have no *valid* complaints.  That being said, this watch doesn't have a backlight and the glow-in-the-dark parts lose their "charge" pretty quickly.  The band is pretty *meh*, but I won't bother replacing it.
