I think it’s a HRM3-SS? Hard to read the micro writing. I also have a new Dual Bluetooth model for the trainer.
I’ve had issues with the Bluetooth on Zwift, but that was software on the laptop and Zwift issues. Strap has been faultless.
I posted on this on the previous Wahoo Tickr dying thread. It’s very difficult, as one person has a faultless unit, the next, horrible. I suspect the original was mostly junk, possibly sealing and QC problems.
My sample size was everyone one I know who owned an original Tickr had them fail quite rapidly. Maybe 4 people total. 100% failure rate. Of the same group of people, all now have the Garmin strap. All still working perfectly.
Again, the very next post will be someone saying they’ve had a Tickr for 8 billion years and they use it to belay climbers on Mt Everest with zero issues… so who knows.
For me and the small group of riders I know, the original version was terrible. I imagine it’ll be a while till we know if the new model is reliable.
