Review: Excellent replacement for the Garmin soft strap supplied with my Garmin 310XT GPS watch - Excellent replacement for the Garmin soft strap supplied with my Garmin 310XT GPS watch. After a few weeks the heart rate signal started to drop out. I replaced the battery, tried electro gel etc all without success. Research on the Internet advised to buy the Polar strap , which I did. Works brilliantly. No need to buy the transmitter (the hard rectangular bit) as the Garmin transmitter clips directly onto the Polar replacement strap. Likewise no need to pair it again. My thanks to Polar and to those who posted the solution on the Internet. Garmin really should sort this problem out as I shouldn't have had to buy a replacement on something only a few weeks old. The hard strap on my Garmin 305 has worked without any problems for years, just the occasional battery replacement which I would expect. 25/2/16 FURTHER TO THE ABOVE The rubber sensors have now started to peel away from the elastic strap giving a slightly erratic reading, so I purchased a replacement only to find the transmitter would not clip on. Thinking the 'poppers' were faulty I ordered another - same problem. I then looked more closely and found the rubber surrounding the 'poppers' was slightly raised compared to the first one I had purchased, so careful use use of a sharp knife (Stanley Blade) I trimmed off the excess and all is now fine. Seems like Polar have slightly altered the manufacture of these straps.
Review: COMFORTABLE & DURABLE - Lasts well over 2 years of constant use - I first bought a Polar Strap as a replacement for the Garmin strap (the Garmin one fell apart after 9 months). Today I've just replaced this Polar Strap with another new Polar Strap and it has over 2 years of constant use - I run 6 times a week, 50 miles per week. It is super-comfortable and I don't even notice it on 15 hour races. Highly recommended for Quality & Performance. I rinse it under the shower after every run, sometimes with a bit of shower gel and leave to dry naturally hung up with my run clothes. I think I've put it in the washing machine twice in 2 years - as I rinse it as soon as I come in from a run it never got that grimy. The only thing is the price has gone up - the one I bought 2 years ago was £9.63, I see they are now £17.50 each! Have bought another one today to keep in a draw as a spare...the price is only likely to rise!

### ⭐⭐⭐⭐ I like that the sensor strip cover the whole strap in ...
*by S***S on 18 May 2017*

This is my second strap in less than a year. I have a Garmin Fenix3 and when the contact pads on the back of that HR strap started to come away, I resented paying nearly 40quid for a new one, so when I found out that this one works, I purchased. You need to use a sharp knife to cut away some of the rubber around the poppers in order for the Garmin sensor unit to snap in place, but after that I found the strap performed very well. I like that the sensor strip cover the whole strap in one piece rather than the 4 pads on the Garmin one. However, sadly after just a few montbs, when unpopping the Garmin unit one day, one of the poppers came away from the strap. I bought a replacement again, but shortly after, I noticed the price of the official Garmin ones have come down too, so next time I'll probably buy Garmin. I'm going to try to be more gentle when unpopping the unit now, but it's a shame the strap didn't last at least a year. I always look after my kit, but I guess you do get what you pay for at the end of the day... Buy cheap, buy twice.
