Taken from past deal, all credit to @KB57 from that deal. $11.92 cheaper this time. Super cool Casio. Note Bluetooth isn't super useful, it only sets the time and alarms some simple step data (see below). It doesn't display messages, etc.

You can get an A1000 for a bit more. I'd just stick to the A158 or A168 for $40.
