3 reviews for Heart Rate Monitor Replacement Chest Strap Compatible with Myzone Strap MZ-3 & MZ-1Belt 2 Pack

    This is a good value for the money with two chest straps. Quality looks good, but unfortunately it is not compatible with my Polar heart rate monitor.

    I have been a regular Myzone user for more than six years and so am currently rated as a Hall Of Fame Superstar on the app. My original chest strap was showing signs of age and although I had purchased a new Myzone replacement strap, I saw these on Amazon Vine and thought I’d give them a try in case someone found my experience useful. After a couple of weeks of use I judge them to be as good as, and probably better than the original straps from Myzone. I notice that they are the same width (30 mm) as the originals, but slightly thinner (about 1.19 mm thick vs 1.32 mm for the originals) and the snaps are spaced for a perfect fit for the MZ-3 module. I ordered a size Large which is a good fit for my 39 inch rib cage under my pecs, leaving about 8 more inches of expansion room if that were needed. Conversely, the adjusting slide could be moved another14 inches closer to the electrodes making the belts about seven inches smaller if needed. With the original strap, the Myzone app was often a bit slow to find and connect to the MZ-3 module, sometimes taking a minute or two in spite of wetting the electrodes. This strap has always connected much more quickly and I would say the strap is more comfortable to wear than the original. I often forget I am wearing it and I was usually aware of wearing the original. I am very pleased with these and find them to be great straps.
