These are some problems about this watch. I have recently adquired in Barcelona (Spain):
Good level of sensor but....
Low backlight level (It could be better as in Casio watches).
Low level of alarm (It could be better as in Casio watches).
It doesn't has Timer.
Rubber
strap not well designed when having to cut the rubber
band. You can only change the diameter in a few milimeters.
For these reasons I can't recommend it to buy anyone.
