I have talked many new riders out of one of these.. My base suggestion is to

ALL vet checks in SE/ and Region 5 NATRC and ECTRA.... YOU MUST turn 'OFF'

ask the vet check Head PR person to take it again.. BE NICE about it .
I have never found the numbers to be wrong on the HRM ..but you never know
