For me it’s been the straps that fail. I originally had a Bontrager and the strap failed and they replaced it and the replacement strap failed too. Then I got the tickr from a friend cause he got it as some zwift deal, and the strap broke.
I ended up ordering a replacement strap from Amazon which seems well made and the contacts are different too, and then wahoo sent me a replacement strap (from the Gen3) so now I have two working monitors, I have the Amazon strap and the wahoo strap, and the wahoo and Bontrager sensor. Just for fun before I toss the old ones here’s a pic, top to bottom. Note how the newer ones all use a flatter sensor pad, the Bontrager strap actually failed where the round sensor pad is moulded in
- Bontrager gen1 (they use a different one now) failed
- Wahoo Gen2 failed
- Wahoo Gen3
- Amazon “PowerLabs”
