Fourth Frontier Reviews 374

I just love this product and company. I recently had some heart issues and would use this product to monitor my progress. I had some issues with the device but were quickly resolved by the Fourth Frontier team especially Sahid. I would definitely recommend this to everyone.

This is an outstanding company that stands behind their product. I had my Fourth Frontier X2 for about a year when I started having some problems with saving data. I contacted the customer service department and they attempted to work through different fixes to no avail. Poonam realized the trouble I was having and setup a return and at the same time sent me a new unit. I received the new X2 yesterday and used it today… perfection! What a great experience I had with this company and their great product. The X2 is an outstanding unit that works incredibly well and their customer service is second to none!

Banti Kumar did a great job of solving my problem quickly. I love my new monitor. Knowing your heart rate isn't enough. Being able to see the P-QRS complex gives real insight.

I contacted the Fourth Frontier support people as I had a problem with my new device. I was very impressed by the way they answered quickly and resolved my issue.
I am using the device to monitor my heart rate as I quickly become ill when exercising outside my recommended zone. I love the way it alerts me if I am starting to overdo my exercise. This will give me much more confidence when exercising and playing with the grandchildren.

After 6 or 7 years my heart monitor has bitten the dust, probably because of my own fiddling. Over this time the unit and the app has been very good, I have enjoyed using this device and while initially pricey its been well worth the money. When I've needed help the customer service has been instant and useful, just what customer service should be. Excellent!

In a cheap price giving a good product

Fitness tracking with great leading metrics to track overall physical health . The premium features really help in tweaking ones fitness plans and . Very useful particularly for an aging body . HRV and VO2 max help in maximizing fitness and stress levels

This device is really GREAT. It always works... connects easy to both my Zwift and Rouvy and reliably gives a real life EKG that is clear, easy to read and is emailable to a physician etc. It breaks down your history very clearly and easily to understand on the app. Everything form training load to heart rate to breathing rate and heart strain to an accurate VO2 max ... worth the money. Highly recommend !!

Great help. Would recommend greatly!

I purchased the Frontier X 2 on 14 Feb 2024. It stopped working on September 8, 2025. I contacted support. Unit was assessed directly by a rep (via online meeting) and determined to be defective. No refund or exchange was issued because unit had not been purchased though a channel Frontier recognise. Even though the unit was authentic, they did not stand by the product nor recalled to inspect closer to determine what had gone wrong. Cost of unit was 450AUD and didn’t even last 2 years. Not great value. Frontier offered a 30% discount on a new unit that on the website is nearly 600 USD (and offered with a standard 25% off). Why would I buy again, even with a very poor discount, based on durability experienced?
If the unit is authentic then stand by it.

I had a charging issue with my X Plus and contacted technical support.
Poonam responsed very quickly and sent an instruction movie how to solve the issue.
After all it was just the led's showed another pattern than expected due to an update to the latest firmware, so not really a technical issue :)

Thanks for the support Poonam!

Excellent product and superb customer service; quick, effective, and solved the issue that I was having difficulty with. Great to see a caring, professional company - I wish more were like that!

Happy to say FF customer service was quickly responsive and resolved my issues completely.

I have Fourth Frontier X2 and it’s brilliant. Particularly with a premium subscription, there’s lots of data to analyse - or you can leave it all the algorithms! A real selling point is the support - very helpful and always wanting to help. 5 stars!

Sahid and the technical team were fantastic. They understood my issue and were empathetic to my dilemma. There was no initial cookie-cutter response that doesn't help anyone. Each communication was responsive and moved to an efficient resolution.

A great product to monitor cardiac performance during exercise - important time as someone with heart issues but a fitness fanatic. Product is easy to use with unique stats. Support team is also very responsive when the occasional issue has occurred - and both times the issues was resolved satisfactorily

Poonam was really helpful in resolving an email issue.
This took many tries and I was emailed back and the follow up was great!

I have had a Fourth Frontier X2 for some time. I am an older athlete. I had some different patterns on the ECG traces during exercise which I wasn't sure about. I raised a question with Fourth Frontier and within an hour got an appointment with one of their medical technicians. On the call she went through all of the patterns explaining what was a trace and what was interference, such as during strength training where chest muscle activity can effect the trace. She also went through very helpfully the other parameters such as HRV, etc.. Really helpful call and hats off to the best customer service I have ever experienced.

The product, the X2, is amazing and just what I needed as I'm a 72 year old former competetive runner, then cyclist for the last fifty years. I have suffered from Afib for the last nine years and continue to exercise and train as before though having the additional information provided by the X2 is extremely helpful for me and my cardiologist. I am most impressed, however, with the personal attention I've received while this old guy attempts to learn the intricacies of this truly valuable product. I have contacted the company several times during my learning curve and the staff, especially Poonam, has been kind, attentive and patient. Always following up to check that I'm satisfied and things are working to my expectation.
I simply cannot recommend both the product and staff highly enough.

Had a great experience with this company, i love the products and the quality of the customer service has just taken it to a long forgotten place, they have been so helpful and attentive in answering all my queries. Customer service is not something we can take for granted, I rarely find it, often not getting responses from companies as they can’t be bothered, not so with Fourth Frontier, their products match their customer service, five star all the way *****
