Have extra alarm on normal watch..
The alarm (Onyx Vibration Alarm) does not really wake you up. So best just to have a normal watch with no sound on the alarms instead as its lot stronger then this. It also took while to get sent and I seen so many other companies have a 1:1 copy of this (guess aliexpress or something). Edit: They were very nice by refunding me the money for this product and making sure I got happy.
