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.

I am used various brands of HRM’s over the years. They seem to last a few months to over a decade. I bought the Cardiosport TP5D because it recommended for HRV testing. It also takes a CR2032 battery rather than a CR2025 and so should last longer between changes. Cardiosport also seems to be a small UK based company, with manufacturing in Taiwan, and so worth supporting. I will continue to update this review as and when I encounter any issues but after several runs it seems very comparable to my Polar H9. The chest belt does suffer from dryness when first setting out even with gel. I think this is because the rubber pads are relatively small. The pod fits all my current straps including Garmin and Polar. A tip for longevity of all HRM’s is to use waterproof tape to seal over the battery compartment. This stops any sweat ingress, which shorts the battery. I will update this review when I change the battery for the first time. For reference I get around 65 hours from my Polar H9 and so with the additional battery capacity I am hoping for a minimum of 90 hours from this. I always use Panasonic or Maxell batteries. Edit: 19/01/26 Battery failure. HRM dropped out during run. Tested battery and it was reading 60% after run and so needs changing after only 8.75hrs of activities. Very poor given the data in the user manual suggest that the standby current is so low that the battery should last in storage for almost infinity! I will return because I don't want to be left with another HRM that eats batteries!! A real shame!

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 was great initially but I bought end May 2024 so just a little over 12 months its fallen apart...literally! The part where you clip on the hrm has come apart as has the back or the hrm itself. It looks like its rusted and gone mouldy inside. I always unclipped and wipe it clean after all my runs but its obviously not enough. I'll have to find something else

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.

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

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

Works perfectly
