I love this strap-free heart rate monitor. Sometimes the optical wrist-based heart rate monitor can't measure quite that accurate especially when we're running so that's why something like a chest heart rate monitor is gonna be something you should look to, especially if you're a runner or you're doing heart rate training. Running with a strap all the time when I do heart rate training it does get a little bit restrictive you kind of feel the pressure around your body. Sometimes I get pretty annoying about it. It's good to have a strapless heart rate monitor when training.

I have no complaints about how well the VisualBeat monitor works. I've been using it a lot and it's giving me useful information. The monitor sensor does need to be recharged frequently. One thing I would definitely want to be different and that would be to have an app available for a Windows based PC, to download the data from the monitor sensor after a ride. I want the data on my laptop and the only way I can do that is to download the monitor on my Android tablet, photograph the screen of my tablet and then transfer the jpeg image to my PC. This sucks!

Ordered this product after my procedure to monitor the heart while I sleep. I brought this to my doctor s visit, and he was definitely sold on its accuracy and asked where he could find it so that he could recommend this unit to other patients. The interface is very pleasing and very easy to use!

Works great when it works, but lately that is not often. Device is recognized by and connects with iPhone Bluetooth but the app won’t recognize it— rendering it useless. Additionally, tech support is absent! I’m very disappointed,

Pros:
- Unique design that can be used with stick-on ECG pads. Stick-on pads are more comfortable than a chest-strap, they conduct better and and they don't slip out of place.
- Many inexpensive options for replacement pads.
- Easy to connect to a fitness watch using Bluetooth or ANT.
- Uses rechargeable batteries, not disposables.
- Chest HRMs are much more accurate than wrist HRMs.

Cons:
- Android mobile app (ViHealth) is useless. Lots of one-star reviews on the Google app store. Could never get it to connect to the HRM.
- The HRM has a vibrating buzzer that goes off when your HR reaches a set threshold. Not a bad idea, except it never stops buzzing until your HR drops again, which gets really annoying after a minute or so. And the only way to adjust this is to use the mobile app, which wouldn't connect! In the end I was able to disable this with a borrowed iPhone and the iOS app.

this is a good gadget.
it would be helpful if this gadget could also be linked to other apple apps so the data collected can be collected and stored in one place

I use other products from Wellue and am very happy with them. Tried this one since I was looking for a heart rate monitor to track heart rate during workout. This product does that and also provides a history graph so you can see not just current rate but how it changed during the workout... it also has an added bonus of being able to show and record ECG tracing. I charged it fully and it was easy to put on. The heart rate monitor seems pretty accurate and is non-obtrusive. It stays in place whether jogging, rowing, etc. Very good information to help me work out better and see how my heart rate trends are improving as I get in shape! It uses the same app as other Wellue products, so no new app to install, and all data is in one place. I highly recommend this product.

Accurate enough for training, best results for cycling and elliptical. As mentioned by other people large arms movements or body for sure will affect the reading, but it`s normal. Keep in mind medical effort EKG test uses sticker electrodes. Useful to detect heart "misfiring" . Usually I`m recording one minute when start the training, another one at max effort, and a last one when finished the work out. Email them as pdf . Check and save them for reference. Decent battery, but time will tell.

If you want an accurate record of heartrate while exercising or through a day, or want to take some ECG measurements, this monitor works well. The chest strap is comfortable but if you move a lot it sometimes briefly loses contact. The adhesive patches almost never lose contact and you don't really feel them. As long as you sweat a bit, they're not difficult to pull off again. Tip - brush the chest hairs out of the way first when putting them on! .
I believe this tracker provides a more accurate measurement than any wrist-worn tracker unless the wrist tracker is extremely tight to the wrist.
For the ECG, you'd probably want to buy some guide to what ECGs should and typically look like otherwise you might see a different pulse but not know what it means, or is just normal variation anyway. But it's an interesting measurement.
The chart could use more gridlines for better readability but is clear and can be saved or emailed (like a screenshot).
Some future features in the app that would be interesting, if the device can do it, would be HRV statistics and download of data for time between pulses (CSV file) for recordings of six or eight hours for my own analysis.

I find it to be extremely accurate (Unlike my fitness watch) which I confirm by comparing the blinking LED to my actual heartbeats from time to time.
I use it every day while on the elliptical.
