Poor longevity

Had this heart rate monitor appropriately 6 months and it no longer works as it should. Reads extremely low. Tried changing batteries etc. but to no avail. Best to stick with the more popular brands and spend that little bit more.

Absolute rubbish and previously used

I purchased yesterday as a brand new item. Upon opening, it was apparent that the battery compartment cover was knawed and battery was missing - obviously a previous return. No instructions on pairing but I eventually figured it out with Strava. The heart rate reading starts with 70 and then shoots to 239+ consistently which is clearly wrong. A poor product and Decathlon shouldn't be selling used, returned goods as brand new. I will be returning this immediately.

Good heart rate strap wrong battery

I've been using my first strap for twelve months which makes it as reliable as my previous Garmin strap (which failed after 18months). I've just brought another for my son but this didn't work. When I checked it had a CR2012 battery rather than a CR2032 battery. I've swapped it for the right battery but putting the wrong battery, which isn't up to the job, in a new product is rubbish (I've checked my strap which came with the right battery).

Hello Richard,

Thank you for your comments about our Dual HR BELT.

I'm sorry that you found a CR2012 in your product, this never happened before. I will make sure this was not start again on our production line.

Please don't hesitate to bring back your belt to the store so they can give you another new one.

If this one is broken we'll make it repair before putting in back to store in second-hand products.

Thank you

Heart rate chest strap - works perfectly

Much cheaper than some big name products and works perfectly - talks to my biking Garmin flawlessly. Comfortable to wear for long rides. Really excellent value

For the money what more can you want?

Worked well with Zwift for HR

Had tried a few other devices to connect HR to virtual cycling app Zwift. This worked straight off the bat

Excellent product

With only a few recent outings, I can say that this product works well. Very straightforward to get connected to my head unit, links easily now automatically. Readings seem to be accurate. Recommended.

Cracking piece of kit.

As this is my second review of this Heart Rate Monitor (HRT), first reveiw must have got lost in the ether. This is a great piece of kit, i use this on my cycling Turbo Trainer, to see what numbers i am producing, this works with Ant+ as well as Bluetooth, i have this working with the Wahoo app on my mobile/cell phone coupled up with a Cadence and rear wheel speedo sensor. I found the best way to use this is to follow the instructions as to wet the HRT contacts, i also wet my chest to ensure a good contact, switch your phones Bluetooth and location on first, pedal to get the Cadence switched on then open the Wahoo app, the sensors are connected and away you go.

Low cost value for money. Occasional signal dropout when used with my Garmin cycle computer means it gets 3 stars. 100% reliable when used on bluetooth with my indoor trainer.
