Disappointed customer of 5 years
Myzone belt didn’t work despite following all the diagnostics and repeated attempts. Had to ask for a refund. I have been using Myzone belts for 5 years but the last 2 chest straps have been very inconsistent in there exercise data gathering and this one couldn’t register my heartbeat at all.

I was thankful to find this replacement strap available on Amazon for my MyZone heart rate monitor. I usually buy them from the MyZone website periodically, but standard shipping takes a while. It's genuine, and works perfectly. This is my 3rd replacement belt in 5 years of near daily use. The quality holds up for a long time. The elastic does begin to give towards the end of its lifespan but since it's adjustable, it's never a problem in getting the right fit. It also takes a long time before it begins to latch on to body sweat/odor. Definitely follow the directives in washing the belt in the sink after every use with warm water, and gently wring it out and air dry. And wash often in the laundry. I usually wash it between 1-2 times a week. Eventually as the belt ages, even soaking it in concentrated detergent/solution won't fully remove the understandable (at least in my experience) and totally normal odor that comes with the build up of sweat after long term use. So I do try to have 2 belts on hand at all times to alternate between through the week. If you need a replacement belt for your compatible heart rate monitor by MyZone, definitely go for it in buying it here. And buy two while you are at it.

The body strap that came with my switch failed within a year. I’ve been tempted to purchase replica but after much consideration decided to go with the original. The product arrived within a week from the US to Singapore.. impressive. So far so good. Let’s see how long this last.

Although I gingerly fixed the issue, MyZone should take better quality control measures on their products!
