The Orange one is more like a safety cone orange, vibrant and fluorescent rather than the more muted tone you see here. Kinda garish and not what I was after. But it keeps the whoop physically on my wrist and so does the main job ### ⭐ Broken piece received *by on Reviewed in the United Kingdom 13 January 2026* It was broken when I received my order. --- ## 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.co.za/products/702943088-ar-labs-whoop-4-0-compatible-hydroknit-wrist-band-fast](https://www.desertcart.co.za/products/702943088-ar-labs-whoop-4-0-compatible-hydroknit-wrist-band-fast) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-28*
