Gave the strap to my wife to use last night at gym.
Worked well. Recorded without any hassles and could monitor the HR zones with ease. I started recording as we started (low HR) so just missed the vigorous workout.. Think next time I'll wait till the HR is in the 130s before starting the record

Also paused it twice between the different machines. Is that the right/best way to do it?
Seeing as the electrodes are in the strap... if that goes and we need to get a new strap, will the replacement polar ones be compatible? Makro probably won't be carrying these devices for ever, so maybe buy a few extra? Hmm...
