My old OG HRM-Run is still working but wanted an replacement strap, initially I was planning to get the H10 strap (strap only without the module) but decided to go for the HRM-Pro instead and give it a try.
The potential issue with all the newer Garmin HRM is that the strap and modules are built as a single SKU and there is no replaceable strap options. So if you somehow damage the strap, you basically break the entire thing.
Did a small short trainer ride yesterday and all seems good, BLE connection to iPad Zwift seems fine as well.
