Great product so far, slightly oversold on battery life

This appears to be a good product, better made than the Wahoo Tickr that I have replaced three times. However, the claim of battery life is a bit overstated. It arrived with an installed CR2032 that was on 40% and is already chewing the new one I have installed. That is fair enough, you just need to go easy on the claim on the packaging.

Unique product, good customer service, but this was a replacement

I really like the Viiiva HRM because of its ability to convert/bridge other sensors from Ant to Bluetooth. This one was delivered quickly and works well. Only removed one star because I bought it as a replacement for one on which the bridging failed, and obviously that makes me a bit cautious. Good customer service though, even though it was out of warranty.

Perfect for what I needed

Required a bridge between devices and Apple TV for Zwift. Used this half a dozen times and it has been faultless.

Comfortable and easy to adjust.

No feedback on battery life as I'm still in the early days of using it.
