Milton Duo DLX 1000 Thermosteel 24 Hours Hot and Cold Water Bottle, 1 Litre, Silver

Water Temperature & Heat Retention: I filled the bottle with water yesterday at around 12 PM, and even after many hours, the water was still noticeably warm. While the brand’s claims may sound a bit exaggerated, in real-world use the bottle performs very well. For everyday needs, the heat retention is more than adequate. Based on this performance, I’m confident that cold water would easily stay cool for an entire day. Hydration: The 1-litre capacity is ideal for maintaining daily hydration. It strikes a good balance—not too small to require frequent refills, and not unnecessarily large. Leakage: There were no leakage issues during use. The lid seals properly, which makes it safe to carry in a bag without worrying about spills. Smell: There is no unpleasant or plastic smell, even after keeping water in it for long hours. This adds to the overall quality feel of the product. Build Quality & Feel: The bottle feels solid and premium in hand. The material and finish clearly indicate good build quality. I had previously purchased a competing product at the same price (not naming the brand), and the difference is obvious—this one feels far superior. Size & Design (1 Litre): At 1 litre, the bottle is well-designed and not bulky. The competing product I tried earlier felt awkward and bulky at the same capacity, with clear design flaws. This bottle avoids that issue and feels practical for daily use. --- ✅ Final Verdict Overall, this bottle does exactly what it needs to do. The insulation works well, the design is practical, and the quality justifies the price. While the claims might be slightly overstated, the actual performance is reliable and satisfactory. For my usage, this bottle is the right choice—and compared to similarly priced alternatives, this one clearly stands out. Adequate, reliable, and well-built.

It is a new design of 1 ltr capacity which looks slight smaller than previous products of same capacity. Excellent purchase as it maintains temperature for both cold and hot and value for money.

Very good Product . This thermos is great for very cold or very hot weather.

Very nice product good

Good Quality

I was very confused before buying this because of mixed reviews, especially comments saying it “only keeps water hot for 12 hours” or even less. I decided to go ahead based on the brand and high number of purchases — and I’m really glad I did. Real-life use: On the first day, I filled the bottle with boiling water at 7 am and opened it a couple of times. Even after 13+ hours, the water was still piping hot. On the second day, I filled it at 4 pm, did not open it at all, and the next morning at 6:30 am the water was still hot enough to make coffee — almost like freshly boiled. Over the past week, I’ve tested it multiple times and it has stayed very hot even after 20+ hours when left unopened. Reviews saying it cools quickly may be due to opening it frequently, as heat naturally escapes each time. The outside of the bottle stays cool; only the cap feels slightly warm, which shows the insulation is working well. If you have realistic expectations, this is a solid, reliable thermosteel flask — perfect for home use, mornings, and even long car trips.

Good bottle

very nice product. Does what is says .

I bought this as a milk bottle to go alongside the Milton thermal flask. Tested with hot and cold water and remained suitably cold and hot for either milk or tea for as long as I needed it. I tested for 16hrs and barely any temperature change so I would guess that it will still be great after 24hrs. It does help to have it filled as much as possible and the lid became slightly warm but never hot. Great style and large as a litre bottle. The litre bottle has the lines around it near the base as seen in the photos. Great value and great product.

Good buy. Everything about it is good.

Keeps the water cold all day. The only thing I wish they could’ve added is a handle especially with this bottle of this size.

Good one as described and heat is there for more than 10 hours, good to buy
