Fits Great, but doesn't keep consistent transmittal.
I was thrilled to get my heart rate strap replaced with a smaller size, fit great! However after a week of wearing it my heart transmitter was having communication malfunctions and would keep my heart reading consistent.  I wore my old heart rate strap hoping that it was just a battery issue, but it worked fine.  I did a comparison from my old soft strap to this one and noticed my old strap had more pronounced button connections.  Maybe this was the issue.  I was disappointed it didn't work as well as I had hoped.  I gave it 3 stars because my transmitter is a year old and even though I had replaced the battery it could also be the problem.  Perhaps if you have a new heart rate monitor the product may work better.
Rating: 3 stars
