Great watch, easy to use, good settings etc. the only thing to mention is the vibration is a on then off then on then off for 20 seconds as the alarm which is quite strong. it is quite good and it does wake you up but it’s different to the expensive one which is more of a soft vibration which gradually gets stronger. still a great simple watch for the price!
