Polar Pro Chest Strap - Heart Rate Monitor Belt

I bought this strap to replace the strap frommy Garmin HRM run. The module from my Garmin fits into this strap fine (see first two photos). The space between the 2 metal connectors must be ever so slightly smaller on the garmin as the polar belt has a very tiny kink in it which can be seen in the second photo. This has absolutely no impact on its effectiveness and can’t be felt at all while wearing it.The problem I had with the Garmin strap is that it would show a very high heart rate between the 2-3 and 9-10 minute mark and then drop down to a normal reading. It would also suffer from spikes in heart rate that were far higher than my max heart rate. You can see these on the third photo.With the Polar strap I’ve had none of these issues. Consistent heart rate readings the increase and decrease as expected with me perceived effort.I’m about 10 runs in now and it’s been rock solid throughout. Can’t complain.

Having gone through numerous replacement straps for a Garmin HRM, this one definitely seems the best.Sturdy and comfortable to wear this strap appears not to suffer the drop outs or inaccurate readings of cheaper options (including the official Garmin offering).Technically, it's not a perfect match for the Garmin sensor but it does fit and definitely works.Watch out for sizing though. You'll probably need a bigger one than you think. I'd normally think that 2XL would be far too big so I thought "M to 2XL" would definitely fit someone that needs Castelli XL or Endura L. But no, this one is only just big enough.P.S. Thanks for the tip "DC Rainmaker. com" (all one word)!

Comfort fabulous - fits well, no seams or raised areas to chafe. No irritation from plastics used.Clasp is excellent. Easy to use and secureHr measurement reliability in use is great.It is consumable / textile - so lasts in proportion to use and care... Wash in accordance to instructions, as harsh washes accelerate wear. Pull the H10 off with care so poppers stay bonded. These will help extend life. I do wish polar would look into durability - other straps do last much longer (although don't read as reliably or fit so easily and comfortably)..

Comfortable strap for my Polar H10, ordered because the one I bought with the sensor was far too small so needed a replacement.

Was having some haywire readings on the hrm : sub-100 bpm readings are fine :) , but am not particularly convinced by sub-40 & sub-30 bpm ones (!!). Changed battery in (h10) hrm unit first, without any improvement. Time (for me) to swap out the not-yet-three-years-old h10 strap, next. Opted for the Polar Pro strap which is very nice and has worked flawlessly today, although an old Garmin strap (still with h10 unit) did the job for a few days, whilst waiting for the replacement to arrive. ’Many thanks’ to Amazon for organising delivery of a second strap, after I initially received a size I hadn’t ordered (these things happen) ; much appreciated.

As advertised good quality polar heart rate strap , I'm very happy with this purchase

Original strap. Looks and feel genuine. The last one lasted me years. Will see about this one.

The best chest strap you can buy. I think.
