Bought this to give me a reading while on a smart turbo trainer. Picked up straight away on my elite Drivo Does the job as intended.

Accurate and comfortable

Bought this to use with my iPhone (6s/iOS 13) and Garmin Edge 130 GPS cyclocomputer, and it has no issues pairing with both. The dual connection is useful, since it uses Bluetooth to pair with my iPhone, and ANT+ to pair with the Garmin. Heart rate is measured accurately.

Kalenji HRM

The HRM has not failed me thus far. I have used it in several long rides and runs and it never disconnected from garmin or Zwift. Not sure how accurate it is as I have no basis. I take it as it is.

Easily connects to Garmin 520

Bought this to go with my Garmin 520 GPS as I sometimes like to train at different intensities. Some of the decathlon sensors have mixed reviews as essentially they are a 3rd party, with even Garmin saying that the seamless integration works best with their own branded products. However, this connected instantly and picked up my HR with no delays or lag experienced. For £30 this is definitely worth buying over a more expensive alternative. Having a spare battery might be a good idea, just in case one of the belts has been on the shelf for a long time but not a huge problem. Decathlon - would be good if you introduced a HRM belt with internal memory, just in case I didn't have a phone/GPS with me. Happy to do some testing for you...

Works Great

Works great, I use it with my Garmin VA3M. No problem with signal and keeps up with interval training.
