Cardiosport TP5D Heart Rate Monitor Chest Strap for Running, Cycling: Dual Bluetooth & ANT+ Compatible with Zwift, Garmin, Strava, Wahoo, Polar, Rouvy, Peloton App

It just works!It is less than half the price of the Suunto HRM, which are only lasting a year before failing.And it works without fuss at the same time as connecting to the watch to my Octane elliptic cross trainer and the Ski Erg. Previously the Octane required me to wear a Polar chest strap along with the Suunto chest strap. The Octane would not connect to the Suunto chest strap without first disconnecting the chest strap from the watch.

Works extremely well and does its job. Only downside in my opinion is the way the strap fastens.

I wanted a modern HRM for cycling and learned that all modern HRM transponders work with all the smart phone apps. I decided to try three models, all of the chest strap type; the Coospo H808s, HiFit and the Cardiosport TP5D. All the sensors paired easily with the apps I tried and worked reliably and accurately (I don't think there is any possibility any of them could be inaccurate provided they stay in place on your chest and maintain connection).Of the three, I liked and kept the Cardiosport TP5D; it was marginally the more expensive - though much cheaper than the Polar or Wahoo - but supports two Bluetooth connections - which I have not needed yet, is the smallest, promises longest battery life (untested) and there is excellent UK telephone support from helpful and knowledgeable staff.

Item stopped working after 2 months and can't be returned. Wasted my money on this product, don't buy.

Bought this to replace my Tickr (which kept dropping out). I had used Cardiosport products in the past with no issues. At a fraction of the cost of the Tickr this has been solid without any issues.

This product does exactly what I need and the strap is extremely comfortable to wear.

Works perfectly
