The charging port for the first two both broke, the second one actually pushed into the battery, and no longer work. I have chronic back pain, if I didn't need the belt I certainly wouldn't be buying another but I really can't afford yet another belt to boot. Buy something else. ### ⭐⭐⭐⭐⭐ good *by on Reviewed in the United Kingdom 23 February 2019* perfect for my heat belt --- ## 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/97454594-7-4v-4200mah-rechargeable-battery-for-arris-newest-heating-waist](https://www.desertcart.hr/products/97454594-7-4v-4200mah-rechargeable-battery-for-arris-newest-heating-waist) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-16*
