Tip: A 4iiii Viiiiva can be used to record your workouts along with your heart rate.
The 4iiii heart rate sensor is a quality tool and, it sounds like a small thing, the strap is more comfortable than others I’ve used. 4iiii is easy to deal with so, thank you.
Device works fine but the storage of data does not work. There is a software failure, according to the helpdesk. Until now it is no corrected!!!! Disappointing….
The heart rate monitor works good. However, I got mine with 72% of battery, the strap is not good, also I requested to be replaced, and it takes a while to connect sometimes.
Love it. Pull it out of the box, slap it on and it pairs with Zwift instantly at ride start. No fuss for the win.
Very good product, soft and comfortable belt, accurate and fast communication with Zwift
