ساعة رصد ضربات القلب لممارسي رياضة الجري ONRHYTM 110

Previously owned a Polar FT04 which was all I needed, unfortunately it gave up on me.
After a little research quickly decided I do not need a watch that tells me what to do and when so reluctantly purchased this device. Don't get me wrong, it's basic, but if you only want feedback of heart rate whilst exercising, this is ideal.
Comparing to the Polar, the chest strap is larger and not so easy to fit. That's me getting used to it. The watch provides decent feedback of effort (heart rate) and have tested over 16 miles, 6.5 interval training and 10.5 at consistent effort. Both instances compared to my old Polar.
I'm in my 16th week of training using 'Heart Monitor Training for the compleat idiot' and can vouch for the benefits for this training (other resources are available online).
Bottom line is, its clunky, basic and cheap. If all you require is binary feedback of heart rate, this will do the job (as long as you moisten the strap pads).

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
