Great experience. Love my 4th frontier.

Great device for ECG, but pretty much useless as a BTE connection to external devices for HR monitoring/readouts. Not precise enough nor frequent enough updates (1 sec update sporadic at best). I always wear a secondary HR monitor to link to Garmin device and/or peloton bike.

Real good. The phone app still has some issues when I put in my height 5’7 it saves it at 6’6 not sure why. Also the heart strain does not show reading when using the app during exercise.

Great product - very accurate. Extremely happy with the reassurance it gives me. To see my fitness improve is very satisfying.

I love the device and so appreciate the information. IN fact, I need it. But I find the device too unreliable to use. I run daily and need to have a heart rate monitor. My battery is always dead and even after leaving it charged and plugged in, most of the time, I can’t get it to start. I reboot it and do what I think needs to be done, but it still doesn’t work. Often it cuts out in the middle of my run and is dead. :-( however, the customer service has been repeatedly outstanding

After a small malfunction in the beginning - which your tech team fixed - it has worked perfectly over almost 200 sessions over the last 7 months. I use it as a monitor for longer, more intensive aerobic endurance sessions.I highly recommend it for those who care about vitals when exercising for safety and track changes over successive workouts.

Outstanding product and customer service

A great hrm that is invaluable as it tells you in real time if you are over straining

A dedicated service, with regular emails updating and requesting information when the device was unused. Appropriate and supportive, and the information derived sent to my consultant at regular intervals.

It has everything anyone needs. It is practical and reliable. I am using it as a training monitor and as a health monitor. I have tried so many from galaxy, Huawei, tag heuer watches and i own 3rd generation Oura ring. All not even close.

I got several normal readings, then felt off and was concerned I was having an episode.. and sure enough it picked up my a change in my rhythm. I am ordering a second one for my wife, we are both so surprised how convenient and well this works without having to wear a holter monitor or other larger devices. Honestly it’s also reassuring and gives peace of mind being able to check when you feel off at any time. I keep it with me. It syncs up easily to my phone and I can quickly download new readings. My doctor was pleasantly surprised with the detailed readouts and he asked me to add notes to the end of each one (standing, sitting, how I feel) for extra home monitoring, then I emailed them to him. It’s easy to add notes in the app to each individual reading. To turn it on you hold down the button for five seconds and then turn it off. Very simple. I researched several of these before choosing this one and I’m glad I did. This is such an easy way to monitor at home and have extra data for your doctor, it really could save your life. Pros: Medically accurate (I do the reading on my chest) and it stood up to my doctors scrutiny. Holds charge well, I don’t need to plug it in very often and I use it daily. Shipped quickly. Very compact and portable, it’s the size of my palm. It's easy for me to take it with me when I go out. Also comes with a simple to understand instruction booklet. Cons: I honestly can’t think of any, for what it is.. it does a great job

it was a learning experience, there's a lot of information to digest, but, I happy to have it all. also knowing my accurate heart rate is comforting, and being able to set the limits a pleasure. with limits set, I don't have to constantly look at a screen. all in all a great experience.

I like the product. I was told that I could get one free consultation. I can't find where this can be set up on web site. I recently received and e-mail with a link to schedule a meeting but the link took me nowhere. Just blank page. Follow up (2022 12/12): FF responded immediately to my inquiry. I had a video conference with a doctor and he helped me set up a meeting with one of their medical outreach experts. I just now completed the 30-minute meeting and it was incredible. The expert was enthusiastic; extremely knowledgeable, and presented the concepts very clearly and thoroughly. I learned so much in the 30-minute session and was very, very impressed. I've change my rating from 3 to 5 stars. Well done FF!

My heart coach (Jaini Patel) is excellent! She reviews my heart data on a weekly basis and makes recommendations for future workouts.

I have the frontier for more than 2 years and I am very satisfied.

Had some cardiac issues and my doctor recommended I get one of these. I live on my own, so whenever I start to feel "odd" I'm always wondering if it's my heart or something else. This device has helped to settle that issue numerous times, has given me a lot of peace of mind, and the data encouraged me to go to A&E three times when it proved that what I was feeling wasn't a false alarm! It's simple, dependable and, at least from my experience, accurate. Sometimes it can't get a good reading, but it clearly tells you that by greying out the background of the graphs. It takes a continuous reading so I just have to strap it on and leave it there. If I see some changes in what I've learnt is normal, I'd head to A&E. The Frontier X app is easy to use and you can add notes to the readings to remind you (or your doctor!) of anything going on like how you felt, what you ate, the meds you took, etc. I keep this device with me almost everywhere I go. You need a device with bluetooth and an internet connection if you want to stream straight to your doctor live.

Everything is good but .... No C port for charging

My husband bought me this heart monitor after I had a heart scare. It allows me to get back to exercise without fear of over-doing things. I know that I need to rest when I get irregularities in frequency. Really great product. Super quality, and a comprehensive app.

Reliable connection with phone; accurate electrocardiograms; good summary and presentation of data

The product does not accurately read my heart rate when training, it gives crazy heart rate values like 40 bpm when i am going full out. I thought it might be the strap, and sent a message asking how i buy a replacement strap but i never heard from anyone.
