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

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.

Thank you so much for sharing your experience! We’re glad our team could walk you through the traces and help clarify things. It’s great to hear that the session was helpful in making better use of the other parameters as well. We truly appreciate your kind words and will continue working to provide the best support possible.

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 *****
