Excellent
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!

This device is really GREAT
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 !!

Stand by the product
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.

We apologize for the issues with your Frontier X2 device. However, it is difficult for us to offer any warranties for devices purchased outside our authorized distribution channels, as we cannot verify whether the device is new, fully functional, or has been tampered with. We do stand by our products and are committed to supporting our customers. As a gesture of goodwill, we’re happy to offer a discount—over and above the standard discount—towards the purchase of a new device directly from us. Please contact us if you wish to proceed with the purchase.

Great support
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!
