Perfect replacement strap
After you original strap gives up the ghost, exact replacement works perfectly.

Fell apart after less than 3 months
I have been using MyZone for quite a few years now and I typically buy a replacement strap every 16 - 20 months. I purchased this replacement strap in mid-March and one of the sensor pads started to peel off after less than three months. Historically I have purchased direct from MyZone but this time I decided to purchase from Amazon to take advantage of free shipping. I am not sure if the version sold on Amazon is a cheap knock-off or if MyZone quality has gone down or if this is a defective strap but I am extremely disappointed with this purchase. Unfortunately the return window has now closed

Rubber Smell is Unbearable
The strap fits well and works as intended, but the rubber smell after just a few uses is unbearable. I’ve tried multiple cleaning methods, but nothing helps. It’s disappointing that a product like this, which is supposed to be used frequently, can’t handle basic hygiene issues. Would not recommend.
