The contents do stay hot on the bottom,but with no lid, the contents quickly cool off. ### ⭐⭐⭐ review *by ***K on Reviewed in the United States on December 7, 2013* It didn't keep the coffee hot long enough. The seller stated that it would keep it hot longer than that. ### ⭐⭐⭐ Just another mug *by S***L on Reviewed in the United States on June 16, 2016* This mug does not keep the coffee hot any longer than my regular coffee mug. --- ## 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.com.sa/products/20260731-hotsmart-keep-hot-mug-patented](https://www.desertcart.com.sa/products/20260731-hotsmart-keep-hot-mug-patented) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-04-23*
