Heart Rate Monitor Armband HRM CHILEAF Heart Rate Sensor HR Sensor IP67 ANT+ Bluetooth 60H Long Battery Life Compatiable for Polar Beat,Wahoo Fitness,SportsTracker,Zwift,Nike+Run Club,X-Fitness, Etc

This armband heart rate monitor is not bad at all. The heart rate shown in the app seems pretty much in line with what I would expect, comparing it to other HR monitors I have used before, like a chest strap or a smart watch. So from that side of things, it seems to do the job. Wearing it on the arm is okay, but not perfect. It was a little too small to fit around my biceps, so I had to use it on my forearm instead. That worked, but after a while it does start sliding down, and I kept finding myself pulling it back up. Bit annoying when you are trying to focus on training. Because of that, I still think chest HR monitors are a little more comfortable overall. They just stay put better for me. This one is easier in some ways, and it connected to the Samsung fitness app without much fuss, which was good. Overall, it is a decent heart rate monitor and the readings seem believable, but the strap fit and sliding make it less comfortable than a chest monitor for longer sessions. Good if you prefer arm based tracking, just check the fit first.

I’ve been using this heart rate monitor armband for indoor cycling and general training, and overall I’ve been really impressed with it. First of all, it’s accurate and very easy to wear. The sensor is lightweight, sits comfortably on the upper forearm, and feels much less intrusive than a traditional chest strap. Heart rate readings have matched closely with other HRM devices I’ve used, and it responds quickly to changes in effort during workouts. Connectivity has been excellent. It paired instantly over both Bluetooth and ANT+, and it has worked flawlessly with every app I tried, especially my favourite which is Zwift, where I’ve had zero dropouts or connection issues, even during longer sessions. I’m not sure why some reviewers complain about it needing an app, as that’s standard for pretty much every heart rate sensor on the market. Battery life is another big plus. The fact that it’s rechargeable, rather than using coin cells makes it really convenient, and it lasts for ages between charges. The USB magnetic charger is simple and works well. The only minor downside is the strap design. It isn’t particularly stretchy, and because the monitor is held in place more by tension than elastic, it can sometimes get pulled off if you’re taking off a tight top or jacket mid workout. It’s not a deal breaker, and it didn't break the connection when this happened to me, but it's something worth being aware of. Overall, this is a really solid armband heart rate monitor: accurate, comfortable, rechargeable, and extremely reliable with Zwift and other fitness apps. A great option if you want an alternative to chest straps and for the current asking price of £39.99 I think it's good value for money.

So the device itself is very well made, easy to put on and works OK (you need to have it tight for it to work properly otherwise the accuracy is off) the problem I had came with the apps u needed to install to use it (it comes with a list of compatible apps) they either were subscription based or I couldn't find the heart rate monitor in them (I just wanted to be able to put it on and link it to my phone and check my heart rate when I wanted) perhaps this simply wasn't the right device for me.

This heart rate monitor is a good quality product. Built quality seems good as well. Its very easy to put on and it works very well. As it is rechargeable, battery hold the charge for good amount of time. It comes with magnetic charging cable which is quite handy. Its quite comfortable and light weight. Its easy to connect with your phone via blue tooth. It is suitable for both indoors and outdoors activities. I am pleased with this purchase.

The heart rate monitor armband came supplied well presented and looks to be made very well. I use my watch for reading and transferring data, and it gives me various readings on the app about how my training session went. Unfortunately, this monitor band wouldn't connect to my usual app, and even though this band can also simultaneously connect to my watch, I couldn't get that to work either. I think it comes down to compatibility, to be honest, but I didn't let that put me off trying this out and used another app of mine called MedM BP. I charged the band up fully before first use, took an hour, waited for the green light to show on the device, which showed full charge. I do like the charging method; it magnetically attaches to the charging base, so no cables to plug in, which can cause damage over time with the connections. The monitor is rather cool; halfway through my workout, the band vibrated. I realised that this was meant to tell me that I was overdoing it based on the data the band was getting from me; this was shown on the readings on my phone afterwards. Of course, you don't get an immediate flash reading whilst working out as I don't have my phone on hand, and my watch won't connect, but if you have an up-to-date watch, then I'm sure this would provide data. I compared data from my watch and this band; the readings were different, not by much, so I don't know which is more accurate; however, I do like that once this band reconnected to my phone, which is automatic once paired to the app, all the data was transferred. If it's a choice between using a watch or this band, then I'm happy to use this band; firstly, it's cheaper plus the charge lasts much longer than my watch, and the band is more comfortable to wear. I've used the MedM BP app for this band, which transfers all the data over to Google Fit, so that way, I've got all my info in one place. I will add that MedM BP won't sync this data without a paid subscription, but hopefully, this will work with any existing paid apps.

This armband works well once it's actually paired to something, but it's worth knowing upfront that it doesn't have a screen or any standalone way of showing your heart rate. You must use an app, which is fine in theory but the experience really depends on which app you pick. Pairing itself was painless. The readings also seem accurate and steady once connected. For the hardware side of things, there's nothing to complain about; it's lightweight, comfortable and the battery lasts long enough that I didn't feel like I had to constantly charge it. The magnetic charger is similar to what you see on smartwatches and works without problems. The software side is the bit that gets irritating. It's not really the fault of this hardware, I guess it's just the nature of trying to get into this stuff without knowing the chaos that is apps. Some apps technically work, but unless you pay for their subscription, you're stuck with limited features. Other apps give more detail without locking everything behind paywalls, some give me way too many ads or require way too much personal information... finding one that plays nicely and gives you the features you expect takes a bit of trial and error.

Connects to popular fitness apps such as Polar, Wahoo,Zwift and more.

I’ll start with the only real positive I found: the heart rate monitor armband itself is well made. The build quality feels solid, it sits comfortably on my arm, and the battery life is genuinely good. From a hardware standpoint, it feels durable and thoughtfully designed. Unfortunately, that’s where the positives end for me. To actually use the monitor in any meaningful way, I had to connect it to external apps, and this quickly became frustrating. The apps I tried were not very user friendly, and setting everything up felt far more complicated than it needed to be. What disappointed me most was that accessing any useful or detailed data required a subscription. Basic information was limited, and anything beyond that was locked behind paywalls within the apps. It felt misleading to have a capable device but be unable to fully use it without committing to ongoing costs. Because of this, the experience felt restrictive rather than empowering. I wanted a straightforward way to track my heart rate and progress, but instead I ended up dealing with clunky interfaces and subscription prompts. Overall, while the monitor itself is well constructed, the heavy reliance on poorly designed apps and paid subscriptions made it not worth it for me. The hardware has potential, but the software experience really let it down.

So far so good. I got this because another Wahoo chest strap heart rate monitor was intermittently not working. I like the long battery life and price. I paired both ant+ and Bluetooth with both of my wahoo bike computers and TrainerRoad on my Windows 11 PC that I built. I used it tonight in Bluetooth with TrainerRoad and it worked flawlessly. There were no instructions for installing the strap but it was pretty easy to figure out. It came fully charged. The only drawback is it has a proprietary USB-A charging device but all units like this have that. I attached some pictures too

Comfortable, connects easily with ZWIFT and is accurate.

This item did not connect to the peleton app

I'll start by saying there ARE free apps, contrary to some reviews I saw about this. Other than that I'm not a huge fan. I don't really understand why it specifically needs an app and doesn't have a standalone screen that will simply show the heartrate on the device itself. I feel like most smart watches have functions like that on top of showing time and a bunch of other functions. This device costs 80$ for me at the time of review but it doesn't seem to have any real functionality at all. I'm one of the rare aliens on earth that doesn't use a cellphone but I have an old one that someone gave me a long time ago. I tried to get some of the apps to make it work but my phone was too old to be compatible with them but i did get one that worked called "Polar Beat". I didn't try looking at the rest of the options since all I need is something that will show the heart rate, as there's no other functionality to this HRM so that app was good enough. It's a jogging app so it will track calories and show a graph of how the HR changes etc. I put it on my leg and ran the app and went to sleep, woke up 9 hours later and checked the results. Average HR of 52 while sleeping. Cool. The battery also lasted that whole time, easily it seems because charging it barely took any time before it was back to full charge. Pairing was easy and instantaneous. The app says 'pair', I click it, it popped up right away, I accepted, the end. Now it was showing the heart rate on the screen and I can click 'start' on the app and it'll record everything the heart monitor reads so I can check on it later. Has training zone times and calorie burn etc. I'm sure you can test out the other apps if your phone is newer than mine, but there certainly are free apps and I think most of them are actually free, for basic functionality. Without an app, this HRM doesn't have any built in memory or anything so you can't just wear it by itself and sync it with your app later to retrieve the data. You really have to have the app do everything, so needing the phone with you at all times and the app on 'start'. Other than that, I tried wearing it over my tight shirt (as I wear long sleeve shirts in the winter), but it couldn't read through the shirt. Since I wouldn't be able to put it under my shirt on the arm, and it's too big to wear on my wrist, I chose instead to wear it on my calves right under the knee. Although it says to wear it on the arm, and might be more accurate on the arm, I didn't find any actual difference on my leg and I quickly forgot that I was wearing it. Since the calf gets bigger after the knee, there's also no chance of it sliding down my leg or moving so I think that'll be my go-to place for it. Since it also doesn't have any kind of display, I never actually need to look at it so having it on my wrist or arm doesn't really serve any convenient benefit. The charger is proprietary but feels really thin, light, and cheap. The HRM and the charger are both so light that lying them on top of each other is hard to keep them connected because the wire is sorta twisted (as wires generally are) so the HRM kinda falls off or flips over. I think I'd probably wanna get some kinda clothes-peg or something to squeeze them together so they won't move so easily. It's not the end of the world, and it's not really as bad as I'm making it sound, but it does feel cheap and inconvenient. There's no locking mechanism that snaps them together, no magnet, so the strap or the wire will generally make it hard to sit flush on top of it to some degree. My final opinion is basically that for 80$ this thing feels cheap and has no functionality or standalone ability. Holding the button to turn it on or off is all you can do with it and, when it's connected to an app, it'll only read your heart rate and that's it. The instruction manual is terrible because it doesn't even name the apps that it's compatible with properly (for example 'Nick+ run club' should be 'Nike Run Club', I think, and I think another one of the apps was also written with the wrong name). For this price I feel like you can get the top brands with a lot of extra functionality so I am not really impressed. It feels more like a 30$ thing but, on the upside, it didn't disconnect or actually have any problems. It charges fast, for however long the charger lasts (because the proprietary rechargers always seem to stop connecting well with their products), and the app data was consistent, and the setup was effortless. So there's not really anything I can complain about other than that for the price a smart watch can likely do the same and a lot more with a lot more convenience and lcd display built in. If you just want a HRM with an app, this seems to work fine, tho I bet you can get a better product at a similar price elsewhere.

The one I got is garbage. It connects to my Garmin bike computer perfectly but powers off after a few minutes. If tried every thing suggest but it never works. Unfortunately I waited beyond the 30 day return window to figure this out.
