## Customer Reviews

### ⭐ Polar support are beyond useless, never bothering to reply to emails
*by R***S on 21 February 2016*

Could not get this to work at all with my iPhone 5s. Polar support are beyond useless, never bothering to reply to emails.I suspect this won't work in the UK, but there is nothing in the documentation to help one.Such a shame as the heart monitor works wonderfully.
