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.

As good as the original one
Bought to replace a strap that started showing its age. I've used it for a few months now and it works perfectly, as good as the original.

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..

I've used Myzone for 6 years now - I find it excellent motivation and it has really helped maintain my fitness levels. I am on a high status level so needed a rapid delivery on a new strap when my old one finally expired. Amazon got it to me the next day without an insane delivery fee as I used my Prime membership. Fantastic.
