    • good monitor but for slack quality control

      Dhirendrakumar (India)
      Used for More than 2 years
      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.
    • Dreadful instructions

      Tim (United Kingdom)
      Used for 1 week or less
      The instructions state that one must follow the intuitive onscreen guide. Complete rubbish !
      The instructions cannot be followed.
      There are not even instructions on this company site
      Thankfully its cheap enough to throw away which is what I will do and I suggest others do not buy it until proper instructions for use are available on this site.
      Nothing as it does not work
      Instructions impossible to follow
      Response of the brand
      Hi Tim, 

      I'm sorry that the instructions for setting up the OnRhythm110 Heart Rate Monitor are not clear. 

      Here are the instructions and some videos:


      If you are still having trouble I can ask one of our product trainers to get in touch and talk you through the set up and use. 

      Please don't throw away - as the product is covered by our 365 day "satisfied or satisfied" guarantee then you are welcome to return your HRM for a full refund. 

      Kind regards,

      very cheap
      not much
    • Good enough for only twenty quid

      jerram (United Kingdom)
      Used for 1 week or less
      Took quite a while and much cursing of Decathlon to get it to read my pulse - but then it all clicked in place when I saw the rain drop symbol on the back of the chest pad - make sure the strap is wetted each side of the main pad, just as the diagram on the back shows. Think this should be made much clearer in the instructions as this seems to be the main problem when trying to get a reading
      not too difficult to use
      Slightly fiddly at first to get used to

      Dan (United Kingdom)
      Used for 1 week or less
      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,
      Response of the brand
      Hi Dan,

      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.

      Kind regards,
