Great quality.
Fits the mz3 and is still going strong after months of daily use. It's definitely worth getting a second strap so you can wash them more frequently. These get popped in the washer and hung out to air dry.

Excellent replacement
Purchased as a replacement belt and wasn’t disappointed as it arrived very quickly and works absolutely fine with my pebble. I would purchase again via Amazon.

Excellent product
Exactly what I needed. I would recommend. Make sure you order the right size though.

Bit tighter than old one.
Bit tighter than the original one, or I'm fa-fItter more muscular than before.💪

Same as original
Great replacement strap, I actually ordered the small as my original strap had stretched and was losing contact, as well as starting to smell on the rubber contacts - I tried everything to get the smell out, washing, anti-bacs, even after bleach, bicarb & vinegar could still smell it so had to buy a replacement, and very happy with this one. After adjusting it fits perfectly, rubber contacts good and presstuds are in the correct place so the monitor clicks in firmly. Please note, this is for the original oval shape monitor not the new smaller, round one.

Myzone Strap Replacement
Great replacement for my old strap that wasn’t working - second time old style with continuous sensor got worn / tore and had detection issues. New design with two smaller sensors seems to be better so far!

Works but doesn’t last long
Bought this in October 2022. Use it 5-6 days per week. These photos are from July 2023. Both sensor pads almost completely coming away. I suspect it’s not a genuine strap, so just be aware you’re likely to only get 6-9 months frequent use from it.

Ordered this replacement strap. It smelled so bad when I received it but I hoped it would go away. A couple of months in and several machine washes later still the same. As soon as I walk in the room I can smell it, not to much mention when working out.. So weird! Such a dissapointment! Never had this issue with my old one byt this one's really bad..
