Apart from it uploading quicker and giving a kcals reading and more connectivity, I found there were spurious readings on the ecg trace which caused me to question its reliability and whether it was worth spending another £300 upgrading from V1. Decision was to return and now awaiting refund from Amazon despite them receiving it back 2 days ago. ## Frequently Bought Together - Frontier X2 Smart Heart Rate Monitor Chest Strap, Wireless Heart Health Monitor with Strain, Breathing Rate, and Fitness Tracking with Continuous Heart Rate Monitoring - KardiaMobile 6-Lead Personal EKG Monitor – Six Views of The Heart – Detects AFib and Irregular Arrhythmias – Instant Results in 30 Seconds – Works with Most Smartphones - FSA/HSA Eligible - Livenpace AI HR Monitor, 24 Hours Chest Lead Device with Free AI Analysis & PC Report, Chargeable Recorder, HHM1 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/619004661-frontier-heart-rate-monitor-chest-strap-accurate-hr-tracking-zone2](https://www.desertcart.hr/products/619004661-frontier-heart-rate-monitor-chest-strap-accurate-hr-tracking-zone2) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-23*
