Cheap, Reliable, irritation free
Used for 1 week or less
I started using this product few days back, it's very easy to operate and tell you your heart rate, calories burn and you can set it according to your body weight height.
The HRM belt is so easy to fix you and it's not irritating at all.
But wishes for more features.
Like it will be wonderful to see time ,heart rate and calories burn at the same time
Battery stopped working in 3 months
Do i need to store the watch separately from the band or switch something off in order to prevent battery wastage?
Atractive price-range, but not so in use
Used for 2 to 8 weeks
After a thorough study in the market, when I had this cute piece of gadget, I was excited to have a test run with it. My decision for going for this product is obviously the price tag. It was even a special discount day in my local Decathlon outlet (Howrah, India). But soon I started getting disappointed. This watch was not able to receive signals from the chest strap.
So next week I had to return to the store. They said probably I was not wearing the chest strap properly. So had a trail inside the store and it did work. I was excited again and constantly checking the reading for around another coupe of hours.
But the more I explored more I'm getting frustrated with this product. I tried this in various places with various conditions and my conclusion is that the signal from chest strap is not so strong or has problem of interfering with other signals around.
If I'm using this in a open ground or remote places or something like this, there is no issue at all. But as soon as I'm in front of any noisy area (with lot of signals - mobile towers, inside a server room etc) the chest strap is not at all work and the watch always complains about no signal. Even inside my home gym it refuses to work.
Hence I feel the purpose of HRM is gone and I'm looking for moving to Fitbit or Polar or Garmin products.
Price, better built than other HRM in this price
Frequent Signal issue between watch and cheststrap

Lost signal issues due to persperation
Used for 2 to 8 weeks
I have had this device for a few weeks and the "Parrot" system in my car was always making it bleep. Very distracting !
Then within a dew weeks I had to change the chest battery and found that the battery was corroded. I guess due to personal 'persperation' at the gymnasium.
The O ring seating is not so clever and despite changing the battery in the chest band the wrist device is informing me that there is 'No Signal' ,,,, more often than not.
It is a pity as it worked well for about a month.
My local store in Tenerife were apologetic .......but ......
Response of the brand
Hi Mike,

Firstly I am sorry for the problems that you have had with your OnRhythm310 Heart Rate Monitor.

Given that the signal was working well and has deteriorated since the battery corroded I believe that the problem is linked to this and that the chest belt is not drawing enough power.

Unfortunately I have no authority over the store in Tenerife but if you are able to return it in the UK then you will have no problem.  You can let them know that you have been in contact with the UK Market Manager and that I believe that, given you have tried a new battery and that this has not rectified the problem that there is  a manufacturing problem that has led to the corrosion and that we should exchange the belt for you.

If it helps reply to my message and I can try to contact someone in the Tenerife store for you.

Kind regards,

Response of the brand
Hello Kristaq,

You have my sincere apologies for the poor functioning of your OnRhythm 310 Heart Rate Monitor.  The connection problem is know and the advice of the product manager for people with a watch that has these connectivity issues is to return it and replace with the new model where these issues have been resolved.  The replacement model is the OnRhythm 500. 

https://www.decathlon.co.uk/onrhythm-500-cardio-watch-id_8389272.html

Please make it clear to the store team or to our customer loyalty team that your watch is defective and that I've recommended that we replace it for you with the new model. 

Kind regards,

Good value but not always reliable
Been using this for a couple of weeks and so far am fairly pleased. Easy to set up and use for interval training. The problem is the heart sensor doesn't stay reliably connected to the watch. Every time I use it I get a beep to say the connection has been lost after 45-60 minutes use. This is sometimes accompanied by the message, 'strap low', on the watch display. The manual is no help- have put a new battery in the heart sensor but problem persists :(
Great watch/HRM

Great value for money and I think better than the similar Polar product as the battery in the heart strap can be changed when flat ( after 18m approx use). Polar has to be sent to workshop where the battery replacement was to cost me £30. This watch and heart strap cost less than the polar repair quote.
Heart strap has replaceable battery
Instructions not easy to understand
Connecting to a PC
Is it possiblt to hook up this HRM to a PC in order to store workout information? I love this watch, but don't really see the point if you can't track your progress or workouts.
Not Accurate and little over complicated

All in all we are not very happy. Partner has a polar FT4 and considering the price difference isn't huge really regret not going for that one.
Inaccurate, complicated to navigate around
