## Description

desertcart.com : MYZONE MZ-3 Physical Activity Chest Strap Heart Rate Monitor - Fitness & Activity Tracker : Sports & Outdoors

Review: Obsessed - I’m obsessed with this heart rate monitor. It is a little picky about resting sometimes… in which case it will disconnect from my phone for a second but as soon as I pull the app back up it will reload and it’s fine. The sensors can be sensitive. In the cooler months it won’t turn on right away so I’ll just warm them with my hands or if you damp your hands with water and then rub the sensors it’ll turn on right away. Other than that I love it!

## Questions & Answers

**Q: What is the size of the belt?**
A: Its adjustable. I am xxl shirt size and about 255lbs and it fits me fine with room to expand it larger

**Q: does this fit really big peoplke or slightly skinny only?**
A: I’m 6 ft 280 pounds.  The strap that comes with it was a little “snug” on me.  I did purchase the XL strap and it fits a lot more comfortable.  But the one that comes with it wasn’t unbearable.

**Q: Does this offer the same information via memory as it does when connected to the phone during exercise?**
A: Hi, Yes, pod will keep 13 to 16 hours of data and will download to your app the minute you connect. It is the same detailed data that you get whenever you are connected.

**Q: What size is the belt?**
A: It's a adjustable belt so it should fit most adults. If your extremely petite or extremely large you may have trouble. I'm 260lbs and have plenty of slack if I needed it larger

Works great. Best physical activity tracker I've used.

### ⭐⭐⭐⭐⭐ Maybe
*by T***N on July 31, 2020*

I loved this when I first got it. I do still use it and I have contacted the company about issues with it. You are only supposed to have to charge it once a year and I got mine in March and I have had to charge it 3 times. It shuts off in the middle of a run and takes forever to come back on. The company told me I would have to send it in and be without it for 3 months for them to look at it. I bought a new belt to see if that was the problem but it still does the same thing. My friend has one and never has had a problem with it and has had it for almost a year and never has charged it yet. I am pretty sure I just received a bad monitor but I notice someone else that I follow hers just shuts off as well. Make your own decision I am not sure about it.
