ONRHYTHM 110 running heart rate monitor watch white

I only use as a HRM. Basically it doesn't work.
The value shown is sometimes feasible, often under-reads (eg. 80bpm when cycling hard uphill).
I have returned one, the replacement is the same.
I changed the battery (after 2 months) but no improvement.
Not fit for purpose.

Lots of people have commented saying their chest strap won’t pair with the watch.

For info: the chest strap needs to be dampened in order to give it a good seal with your chest, which is what the water drop sign on the back of the strap refers to - this isn’t an indicator or water resistance.

I tried it at first when it was dry and it didn’t pair. I then moistened the strap with a little water over the rough rubber bits and it paired instantly.

Fantastic watch for the price and much more accurate than a wrist-based heart rate monitor - would definitely recommend this.

Obviously it stands to reason that the people who couldn’t get their watch to pair could be encountering other issues, but my guess is that this was actually the issue!

Cheap but NOT cheerful. Useless instructions. Didn't work. I suggest you avoid this product. I've been stuck in Gibraltar in lock down so can't even take it back!
:-(

I bought this after failing to find my Garmin heart rate monitor strap and needing to replace an old Kalenji watch that still works but the strap has failed after 4 years. Can't see that it can be replaced.
This product works well and the transmitted signal is even picked up by the gym machines. It is a pity is does't get received by my old Garmin watch.
An excellent product for the price, well done

I bought this to approximately measure my HR whilst running.

However, I cannot get the chest strap and watch to connect and produce my HR. I’ve tried on the treadmill and out in a park. I’ve tried with and without wireless earphones. (All of which apparently ‘could’ affect the connection). Still no joy.

I didn’t expect much for the price, but I did expect it to work.

If you buy this, you will be wasting money.

Does what it says on the box,if you want Basic HR without the bells and whistles this is the one for you!

Measures heart rate, time at exercise, target zone, live only, does not record session or time in target zone, large easy to read display, shows current heart rate or time of exercise or time of day. Good training aid.

Great product very impressive

there is no communication between watch and heart monitor, item returned

Only recently purchased. Wear at gym during excercise. Reasonably easy to navigate functions, accuracy good. Also works alongside gym equipment.
