Heart Rate Monitor Arm & Wrist Strap Compatible with MYZONE MZ Switch Arm Strap Replacement

I used this with a Polar Verity Sense, not a Myzone. The only issue was getting the old armband off without damaging it just in case this armband didn't work. The polar armband has a metal part that adjusts the length. After less than a year it had white gunk building up on it. It looked like a reaction from sweat and the aluminum. The elastic still had some stretch but it wasn't great. Once I removed the old armband this one went on easily. I would like a bit more length (maybe let the buyer trim it to size with scissors?) but it's still long enough for my larger arms. If you have really large arms this might be too small. While it is stretchy it could be a bit more. I wear it low on my arm so when I flex it doesn't need to stretch much but I also have it sort of loose. Tight enough so the monitor works fine but not that tight. The velcro grips very well. So I just undo one side (while leaving it looped through the sensor housing) and slide it over my wrist and elbow. Then I simply snug it up and stick the velcro.

This is a good product that uses Velcro at both ends to secure it. I have a small wrist, and this is way too long for me. I have to stagger the band and slip the Velcro under the other side to make it work. (Photos included.) Wish someone would make a shorter version.

This armband is fantastic! I love it! I get tired of wearing my MyZone chest strap, and this is a great alternative that's a fabulous value. I like buying from Rich Green Valley because their straps are well made, so I knew the armband would be, too! Their quality is great- the armband is durable and comfortable to wear. There's enough velcro to adjust to the size you need. My MyZone device fit perfectly onto the armband.
