A fantastic device rugged and water resistant. Had initial hicup of HRM strap not working. Went to Decathalon Store. The staff were polite and identified that the button cell in the HRM strap had died out. They replaced the same and since then the product is doing what is is supposed to do. Heart monitoring (BPM) is quite accurate.
Worth buying this product.
Good quality product. Very easy to use and unique. For the first time I'm seeing this.
It is a good HRM for the price , good after sales service provided by Decathilon. Have been using close to 2 yrs ,I guess the transmitter in the chest strap has poor water protection,the back cover does not
close properly .The stop watch function is not clear ,after starting it
can not be stopped with any obvious combination of buttons.
For a senior citizen (70+) it is an useful aide to track level of exercise.
Ease of use and alarms -bpm out of range.
poor documentation and possibly lax supervsion.
Easy to use.
I tried for half hour to measure my heart rate and it was displayed only one time. I run on a running machine and my heart rate was going high enough but still not picked up.
has good display
heart rate not picked up. difficult instructions,
I have checked with the product manager and he has made me aware that when using the OnRhythm110 Heart Rate Monitor it can be effected by other products giving off electromagnetic waves. This could include mobile phones or possibly on the running machine if that was also transmitting information.
If for any reason it does not work in a more isolated environment you are more than welcome to return the product to a Decathlon store. If you often run on treadmills a coded HRM could help as these are less likely to be have interference from other sources.

After over 30 attempts only detected my heart 3 times. Instructions how to set time and date not as straight forward as they could be. I took mine back and changed it for the GEONAUTE ONrhythm 410 Progress HRM. Problems with that also.
Could not detect Heart Rate
Thanks for giving us your feedback regarding the Onrhythm 110 Heart Rate Monitor.
I'm sorry to hear that you had issues with our product and I apologies for the inconvenience caused.
For your information, when your heart rate is not detected properly you can moisten the belt and this should improve the connectivity in between the watch and the sensor.
Regarding the Onrhythm 410 I invite you to go on the link below where you will find videos with complementary instructions to set the HRM and adjust your personal settings:
If you are still unhappy with the product you still can get it exchanged or refunded at your closest Decathlon branch.
I stay available if you have any further questions .
Have a nice day,
Cyrille Simon UK Market Manager DECATHLON
I wasn't really sure I needed a heart rate monitor, so I found this model's predecessor, the 100, on clearance, so I took a chance. And am glad I did!
It is great to be able to tailor exercise to one's heart rate - keeping within the body fat burning band for example - and to see how quickly one recovers from intense exercise.
The booklet will help you work out your maximum heart rate (easy) and your body fat burning band (not so easy).
I don't see why you would need anything more complex - b
Ease of use, simplicity, instruction booklet.
Quiet beep sound.
