as its giving too many parameters and being Ultra Distance Runner with BP. & Marathon Coach , Mumbai India . so its great tools for me to monitor my Heart and now i can train better and safest way. also i suggest my students and track their progress too.

The technology on this device is spot-on. The data is meaningful for any person who wants to see beyond heart rate numbers. The best/accurate sleep tracker as well. Just note that if your device has a USB as a connector, this will eventually rust. Do your best to keep that sealed, dry and away from any sweat and humidity. I am updating the review to 5 stars given that the device has worked very well. Old review - I have used this device for about 1.5 years every day. I am an athlete and I find this to be a great update from a typical heart rate monitor. I have measured the HRM and compared it to others and it seems to be within 1 beat of the typical Garmin HRM chest strap.  What this device excels is in the ability to capture  high-resolution EKGs data while exercising or sleeping. This can help understand how stress affects your heart.  Sleeping capability is useful to understand recovery.  This is not a small device - it is about 2 x thicker than a typical HRM chest strap, so keep that in mind.  It works for me. The device provides EKG and you will need to become knowledgeable to understand what is "normal" or you'll need to seek someone that does.  This device is not going to give you advice or recommendations on your EKG.  When it finds not-normal activities it flags them, however, that does not mean that is a problem...it just means that it is not 'typical'.  There are books like "Rapid Interpretation of EKG's by Dr. Dubin that can be helpful. However, even so, different types of exercise can lead to "non-normal" EKG so you may need to research specific situations as an individual. I have not confirmed that the EKG is reliable.  While it seems to be true-to-form, I have not benchmark it against a medical grade device.  However, one of this new company devices just received approval as a medical grade device, so it does give me confidence that they have the depth of knowledge for accuracy. Additionally, it has extra measurements that can be useful such as heart strain (millivolts), HRV, and breathing rate.    When recording exercise outside, the app actually shows both Garmin and phone GPS data in its own app.  Not that it is critical, but it is nice to have for a quick view.  It also estimates calories, however, that seems inaccurate - especially when resting.  Its calorie estimates seem repeatable, just not accurate. For outdoor exercise, the calorie count is +10% from Strava (which is also an estimate), thus that seems more credible.  Still, I appreciate the company is trying to provide data and I hope they improve those numbers. The battery life is very generous and will last 24 hours of continuous recording. However it is best to record specific activities so that they can be grouped and compared rather than one long stream.  Charging is very quick as well. The Bluetooth performance is excellent.  It has multiple channels and has been very reliable, something I can't say for other Bluetooth devices. The company customer is responsive.  They do know enough to address the device capabilities. The company is actively addressing bugs with updates to the device firmware, mobile app and website.  Additionally, they do add new features (e.g. calories burned) It is the best HRM for an athlete that I am aware of. Thus I highly recommend it. Positives:   > high-resolution ECG continuous 24 hours and while exercising > Excellent battery life > Excellent charging > HRV > Strain/stress,  heart mV > Multi-Bluetooth channels Negatives: >the device will only record down to 35 beats per minute, so if you are below that...it will show 35 as the lowest BPM. I hope that they can lower this limit to 25 BPM.

First of all, I really like the Frontier x2 heart rate monitor with ECG. Second, the customer service is excellent. Every encounter I've had with them has resolved the issue and in a short amount of time.

It's a very good and relevant gadget for understanding the traits if your heart especially after 40. I am late entrant into the running at the age of 44. I realized that it's better to understand whether I am pushing myself beyond my capacity or not. The parameters keep on letting you real-time information like heart rate variability, strain, cadence etc. It has an internal algorithm to keep the limits on the parameters based on your age, weight etc. Very satisfied with the product.

After finishing my Cardiac rehab recently, I purchased my Frontier X to help monitor my heart rate as I continue to recover. My therapist in rehab recommended this model over the cheaper ones. I am really glad I spent the little extra money to purchase a Frontier. The statistics and graphs that are emailed after each workout (whether it is a walk, pickleball or work in the Gym) are emailed immediately (with the ECR) after I turn off the monitor. This monitor does more than just heart rate, it has Breathing rate, heart strain, and training load to just mention a few. All this information is easily printable to take to a doctor to look at. I HIGHLY recommend a Frontier X Heart monitor!

The Frontier X2 is outstanding. As a retired emergency physician, I can attest that the quality of the tracing printed out as a pdf is excellent even during vigorous exercise. It will not allow the fine interval measurements that a medical monitor can, but it is close enough, that I will be able to easily identify any serious irregularity. The app allows one to see rhythm without printing it out. One can even send live real time rhythm to a friend or expert while one is exercising. While the target audience is high performance athletes, there are other excellent uses. Basically it is the lowest cost way to do frequent ambulatory monitoring for arrhythmias, irregularities of heart rhythm. This is what a holter monitor does. I am a retired emergency physician who is morbidly obese. I am on a less than 800 calorie/day diet for rapid weight loss. One of the rare but very serous potential complications is serious cardiac arrhythmias or even cardiac arrest. This is caused by serious abnormalities of electrolytes, minerals in blood stream. Even though I am a physician, the cost of recurrent holter monitors is extreme. With the Frontier X2 I am able to monitor for up to 24 hours at a time multiple times a week. I have picked up a pattern of arrhythmias, but fortunately, they are not serious and only need to be occasionally monitored to be certain they don't progress to a more serious form. With the frequency that I want to monitor during extreme dieting (I am cautious with my life risk) I will easily save well over a thousand dollars over the next several months. I do have the advantage as an emergency physician that I can interpret the rhythm strips & know when I need to see my doctor for any issues. With the internet and additional effort, one doesn't have to be a doctor to get a pretty good idea of what the rhythms are showing. One can use it if they go into & out of atrial fibrillation if they don't have a smart watch the does cardiac rhythms with the advantage that much longer periods can be monitored.
