    The Blink Armband has been a perfect solution to my desire for an accurate heart rate monitor where I didn’t need to wear a chest strap. I would recommend this to friends

    I enjoy using my Blink Armband because it is easy to use and I do not need to wear a chest strap. Plus, the free Heart Zones Training app allows me to save and track my workout real time. I highly recommend this to my friends and anyone else looking for a trustworthy sensor.

    Wait you can receive a accurate heart rate without having to wear a chest strap? Sign me up! Well I received the Blink 3.0 and my runs have never been better. I have the ability to manage my heart rate synced up directly to my Garmin ForeRunner 630. I’ve been needing this for quite awhile now. Easy to use and holds a charge for several hours. The flashing light colors are easy to read and will target your heart rate zone. Paired with the app the Blink 3.0 becomes deadly!

    The Blink 3.0 is the most comfortable heart rate sensor you will ever wear! Not only does it come with its own app, it also syncs with a variety of other apps and devices. I love the different colored flashing lights (or “blinks”) that indicate how hard you are working. I’ve never had an issue with it losing my heart rate during exercise as I have with other devices. I would definitely recommend this product.

    Love using my Blink 3.0 on runs and in the gym. I can see the flashing light indicating my zone easily while running. I find the armband very comfortable to wear. I use it on my forearm or my upper arm and both are comfortable and accurate. One of my favorite features is how easily it pairs with my Garmin 630. I would definitely recommend this to other athletes.

    The Blink 3.0 was a game changer for me! I’m so happy be free of an uncomfortable chest strap. The monitor slips right on my forearm so I can see the colored blinking lights and adjust my workout accordingly to stay in the desired zone for maximum workout benefit. I love that I can use it with a variety of popular apps. The Blink 3.0 has been a constant fixture on my arm all summer when heat takes a toll on my running performance. By watching my heart rate I can back off my pace accordingly. That is priceless. Great product!

    LOVE that The Blink 3.0 is not a chest strap. I’ve worn it on my forearm and upper arm and prefer the upper arm. The strap has never caused my to chafe like the chest straps have. I’ve paired it with mapmyrun on my phone when I’m on the treadmill and Garmin 220 when I run outside. I can’t wait for them to come out with an Andriod version of their app. The blinking colors on the device help you know what range your in, which is helpful.

    I LOVE how easy the Blink 3.0 is to use! I don’t have to worry about numbers and can easily glance at my wrist to know exact what zone I am in! It was so easy to set up and GO! I don’t have to worry about wetting sensors or getting it to stay put under my sports bra! Highly recommend!

    I’m in love with the Blink 3.0! It is the most comfortable HR monitor I’ve ever used. It’s ease of use and accuracy is unbeatable. I’ve paired it with several apps, my Samsung Gear smart watch and the LifeFitness equipment at the gym. I love that a quick look at the blinking lights will let me know which zone I’m currently in and can adjust my effort level accordingly. A great product, versatile and invaluable for those who want to HR train!

    I LOVE my Blink 3.0! I really like that it isn’t an uncomfortable chest strap. You wear it on your arm and it’s so lightweight and comfortable that you don’t even realize you are wearing it. I love being able to see the flashing lights that tell me what zone I’m in. That helps me to stay on track during runs or workouts. It comes with it’s own free app so you can sync your data right on your phone or device. And it’s great that the data is so easily and quickly accessible. It was very easy to set up and it’s simple to use. I would highly recommend this heart rate monitor to any athlete!

    I have owned the Blink 3.0 for several months and must say this is my go to HRM device. The Blink and I have logged hundreds of miles on foot and cycling throughout the Virginia countryside. With a push of a button, the Blink quickly syncs with my Fenix3 and provide very accurate data throughout my work/race. The adjustable cloth band is comfortable on wrist and forearm for the duration of my workout. After my workouts, I just rinse the Blink off and place it on the charger, so it’s ready to go when I am.

    I really enjoy using the Blink 3.0 during my workouts! The arm strap is a way better alternative to a chest strap that doesn’t leave chafing. I keep track of my heart rate zones and workouts through a convenient app on my phone. I would recommend this for others who want a heart rate tracker!

    I found the Heart Zones Blink 3.0 to be very easy to use! It did a great job recording important and useful metrics from my workout. I used it on a couple of runs both indoor and outdoor. Unlike some fitness wearables it still accurately recorded my distance when running indoors. That is a huge pet peeve of mine when your running distance is not accurate when on a treadmill verses outside. I am happy to say the Heart Zones Blink 3.0 recorded accurate distances for indoor workouts.
    Another favorable aspect about the Blink 3.0 is to visually see time spent in the different heart rate zones. It is very helpful to see on a graph if your warm up was too light or too intense. Also when you think you are pushing the pace you can see what heart rate zone you are truly in and gauge if you need to increase or decrease your effort level.
    The wristband material is breathable and easily dries following my workouts. It includes a USB charger and an additional larger strap. I like that the Blink 3.0 feels lightweight to wear. The strap is easily adjustable during mid workout. I really like that there is not an annoying chest strap. The Blink 3.0 is lightweight and I never even think about it being there when working out. A really cool and unique feature is that it flashes the color of your heart rate zone while you are exercising. So amazing to have instant training feedback!

    My Blink 3.0 has been awesome so far! I’d been wanting a HRM but didn’t want to wear a chest strap. I’ve been wearing my Blink 3.0 on my forearm and not only does it seem to get accurate readings, but it’s also super comfortable! The data I get in the free HeartZones app is great, and I found the setup video on the HeartZones site very useful as I got my Blink up and running. I’m looking forward to using it more as I train for upcoming races!

    The Blink 3.0 has become a great workout partner for me. It does an awesome job of tracking my heart rate and helping me with my fitness goals. Plus, the app is super user-friendly and easy to keep track of progress and goals. Every time I have gone for a long run using the Blink 3.0 it has been very accurate compared to other fitness trackers I have worn. All the equipment is easy to wear too, I know I used to shy away from HRM like this because they can be bulky and uncomfortable but the Blink is easy to adjust and I honestly barely know it’s there. I look forward to tracking my progress and getting better prepared for upcoming races with the Blink 3.0.

    The Heart Zones Blink 3.0 has been a welcomed addition to my training. Set up was very simple and feedback has been extremely accurate. The Heart Zones app interface is also very user friendly, intuitive, and provides exactly what I’m looking for, both in a real time and historical environment. The Blink has even a value add to my fall marathon training. LOVE this product.

    The Heart Zones Blink 3.0 has become an integral part of my training! I have a chest strap that I was normally unwilling to wear because it’s uncomfortable and would slide around. No more! The Blink 3.0 is so comfortable and it stays exactly where it’s supposed to on my arm! Plus, it really makes it easy to actively see which heart zone I’m in so I know if I can push more or if I need to back off. Using the heart zones to understand my training has been a game changer and I’m in love. Added bonus – it’s still comfortable even under a long sleeve top and I could still see the light blinking! That has to be the coolest thing ever.

  18. Rated 5 out of 5


    I appreciate that I don’t have to hit a bunch of buttons or tap my screen to check my heart rate. The blinking light allows me to see which zone I’m in with a quick glance. The Blink 3.0 is comfortable, easy to use, and accurate! I use it everyday.

  19. Rated 5 out of 5


    My cardio of choice is running. I can recognize without using a heart rate monitor when I’m in varying zones. But I’m sidelined with injury and I’ve started to cycle instead. The Blink 3.0 has been a game-changer for me on the bike. Instead of struggling to make sure I’m working hard enough during my workouts, I now have the data to back it up. I know when I’m in the zones I need to be in for maximum cardio benefit which has taken quite a bit of mental anxiety off my workouts! I can’t wait to use it on my runs as well.
