1 pointI was supper excited about this altimeter as it had everything I wanted. Unfortunately, my experience with it has been horrible. I've had this for over 1 yr now the NMU is still not working (PC and MAC), and poor battery life. The costumer service is very poor. I have called and sent them numerous e-mails with no responses. Would not suggest this Altimeter or company to anybody. Will not buy from them again.
