My husband is a truck driver and he uses it for his coffee creamer. Very well insulated. Keeps it cold all night. ### ⭐⭐⭐⭐⭐ Great for next day Hot coffee *by on Reviewed in the United States August 23, 2025* Keeps my coffee hot for over 24 hours. I over heat the coffee first it keeps longer then 24 hours.The only thing is that it holds an oder. Best way to wash it is use bleach soak over night. Great value good size works well and leak resistant. ### ⭐⭐⭐⭐ Good Quality Bottle, But Doesn’t Stay Hot for Full 24 Hours” *by on Reviewed in the United States November 12, 2025* The bottle looks great and feels sturdy. It keeps my drinks hot or cold for a good amount of time, definitely works well for daily use. However, it doesn’t really last the full 24 hours as mentioned — more like 10–12 hours for hot water and maybe 15–18 hours for cold. Still, it’s convenient, leakproof, and easy to carry. Overall, a good product but the 24-hour claim is a bit overstated. ## Frequently Bought Together - Milton Elfin 300 Thermosteel 24 Hours Hot & Cold Water Flask, 300ml, Silver | Leak-Proof | Easy to Carry | Office & Travel Flask - Milton Thermosteel Flip Lid 1000, Double Walled Vacuum Insulated Thermos 1000 ml | 34 oz | 1 Ltr | 24 Hours Hot and Cold Water Bottle with Cover, Stainless Steel, BPA Free,Leak Proof | Silver - Stanley Classic Vacuum Insulated Wide Mouth Bottle - BPA-Free 18/8 Stainless Steel Thermos for Cold & Hot Beverages – Keeps Liquid Hot or Cold for Up to 24 Hours --- ## 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.us/products/47260703-10-oz-insulated-flask-leakproof-stainless-steel-water-bottle-milton](https://www.desertcart.us/products/47260703-10-oz-insulated-flask-leakproof-stainless-steel-water-bottle-milton) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-30*
