    • Most accurate & engaging heart rate monitor
I’ve struggled for years with Fitbit and other fitness trackers to accurately measure my heart rate during exercise and this is, by far, the best one. My gym also has a MyZone board, so it’s actually pretty engaging and motivating to see my heart rate and effort in real time. Sometimes the initial connection takes a few minutes, but that’s fine, it always connects and usually connects as soon as my heart rate gets higher at rest. The other issues I’ve heard are related to effort vs. heart rate. I feel like mine is accurate but some of my other gym members have had to adjust their settings to make sure their “90% effort,” as measured by the app, is actually 90% effort in real life. ... show more

    • Wise workout

A good belt to control your heart rate during workouts. Easy to use, comfortable to wear. Long lasting battery. You can wash it when needed. After all workouts you receive the report about your results at your email. Absolutely like it

    • Great product easy to use
Definitely recommend if you’re looking for an HR off your phone telling what zone you’ve been training in etc. etc.

    • Defective
This device won’t hold a charge more than a couple or weeks no matter how much or little I use it. Contacted the seller and they have not been helpful. Buyer beware! Super disappointed as I’ve never had an issue when purchasing through myzone directly.

    • Tips for use! :)
I just purchased this fitness tracker and was having trouble getting the belt to turn on. It would beep once to turn on and then beep three times to turn off. After contacting technical support, I learned that you have to be moving after putting on your belt (not at complete rest) or it won't register your heart rate. Also, try moistening (lightly!) the black pads on the BACK side of the red strap. I was SO confused when they said "moisten electrodes." This helped! I've only had this for a few days, but I'm really loving its accuracy and information! The calories and heart rate are SO much more accurate than my Fitbit Alta HR. I only knocked off one star on my review because it was a bit complicated to understand at first. My advice is to take your time to read the instructions and visit their website. It's worth your time. I'll be back after a few months to update if it's still functioning as well as it is now! ... show more

    • I Don't Run Without It!
This device is great! It's super easy to use and helps me track my runs in ways I never could before! I simply put it on over my chest (it holds its position very well throughout my run, I never need to adjust), and start the workout on the mobile app! It records my heart rate very accurately, because I can personally feel when I am and am not using much energy and it records those moments exactly how I felt them. It's a great tool to use when you're trying to try at certain heart rate percentages. The data comes back in easy to visualize bar graphs which I love. It also has a feature where you can add a picture to every workout which I think is pretty cool now that I've been using it for a few weeks - It's nifty to see the sweat I worked up! Also have literally not had to charge it once yet. Battery life lasts for months, it's incredible. I always bring this with me when I run now! ... show more

    • Much more accurate
My wife moved from a MZ-1 to this MZ-3, and there is a wide improvement. Being rechargeable is one of the main benefits, but the accuracy is what she enjoys the most in the first few days of use. The manual says you will get up to 300 hours of use between charges (depending on how it is used) and it appears that will be the case. ... show more

    • Allows me to push myself to the limit without overdoing it.
I bought this monitor at the recommendation of my trainer. No complaints at all. The app is great and the strap is easy to put on an comfortable. I have been using it a few times a week since I bought it months ago and haven't had to charge it yet. Pretty cool.
