4iiii Viiiiva HRM ANT+ to BT Bridge

Unfortunately there were data errors in 5 out of the first 6 workouts I tried (either HR dropouts or HR spikes), despite following the instructions carefully, and once it had failed the first time, I tried: super-wetting the band, using electrode glue, rotating the box partway to the side, changing tshirt, changing sportsbra, and any other tricks I've learned that may apparently help to eliminate such things. Sadly I won't be using this product again.

Pros & Cons

from the beginning a lot of connection problems. rpm combo with heart rate, which i bought it for, does not work. The app no longer finds the heart rate monitor, and now my phone and wahoo Kickr don't either.

Pros & Cons

Sees my cadence sensor but won't connect, unknown device according to Viiiiva app
