The 4iiii Viiiiva is equipped with the so-called Beat-To-Beat system, a renewed and optimised heart rate measuring system that makes the Viiiiva up to 10 times more sensitive in registering your heartbeat than other heart rate monitors. As such, it ensures highly accurate heart rate data, which is ideal for cyclists who demand a lot of their cycling gear. In addition, the Viiiiva is very user-friendly and has a great memory: it can store up to 65 hours of training data.
Plus, you'll have access to convenient 4iiii training tools like 4iiii PRECISION and Sportiiii coaching with the Viiiiva. These tools help you to easily and clearly keep track of your training data, so you can optimise your training schedule. Do you also work out at the gym? You can also pair the heart rate monitor with cardio exercise machines, ideal if you want to train with heart rate data at the gym. You'll enjoy all the conveniences of the Viiiiva heart rate monitor for up to 200 hours with the included button cell battery.
Want to pair all your ANT+ sensors to a Bluetooth device, like an iPhone? And do you want to have all your data in a central place during a Zwift session? Then choose the 4iiii Viiiiva HRM ANT+ to BT Bridge!
ANT+ to Bluetooth Bridge
This heart rate monitor enables you to easily collect data from other ANT+ bike sensors, like a bike computer, speed sensors and cadence sensors. You can then forward this data to your iOS or Android smartphone or tablet via Bluetooth. This way, you have all your data in one place, which makes the Viiiiva perfect to use in combination with your turbo trainer. You won't need an ANT+ Dongle anymore.

Good reliable HR band
Works perfectly, unlike the original Garmin band and the Xand band. Both worked intermittently on the Tacx trainer. So this one works perfectly!

1 / 5
Nice belt but poor data quality (dropouts and spikes)
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
4 / 5
Does what it should but is difficult to work with the app, etc.
After much trial and error, I got it to work as an ant+bridge for the phone.
