The BEST Thermos I've Ever Owned! - Milton Thermosteel is a Game Changer!
I'm absolutely blown away by the performance of this Milton Thermosteel bottle! I've tried countless thermoses over the years, and this one blows them all out of the water. The biggest thing for me is the outstanding heat retention. I'm a big coffee drinker and I love to take it with me on the go. Recently, I took this bottle on a long road trip. I filled it with piping hot coffee at 6 AM, and by 2 PM, it was STILL steaming and incredibly hot! I was amazed. No more lukewarm, disappointing coffee hours into my trip. This bottle kept my coffee at the perfect temperature for a ridiculously long time. It saved me so much money and hassle of stopping for refills! Beyond keeping my coffee hot for hours, I also appreciate: Durable Construction: The bottle feels incredibly sturdy and well-made. I'm confident it can handle the bumps and bruises of daily life and travel. Leak-Proof Design: No leaks! Even when tumbling around in my bag, I haven't experienced a single drop. Peace of mind is priceless! Easy to Clean: The wide mouth makes it easy to clean thoroughly, preventing any lingering smells or buildup. Sleek and Stylish: It's not just functional, it looks good too! The stainless steel design is modern and understated. Versatile: While I primarily use it for hot coffee, I can see myself using it for cold drinks in the summer as well! If you're looking for a thermos that can keep your beverages hot (or cold) for hours, is built to last, and is easy to use, look no further than the Milton Thermosteel bottle. It's an investment you won't regret! I highly recommend it. This bottle is a true game-changer!

How Hot is Hot?
The main reason I bought this thermos was the pour spout. It's much handier than unscrewing the lid. It does leak a little, maybe it comes out through the spout? Not sure, but I don't travel with the thermos, I just use it to store hot water for later use throughout the day, so I don't have to fire up the tea kettle again. The product description says that it keeps the contents "hot" for 24 hours with no heat transfer. Not sure what temperature is being used to define hot, but I conducted readings over several days using a Pyrex digital meat thermometer. The first measurements I took were from first filling the thermos with boiling water, screwing on the lid and cap, and taking readings every two hours. I was going to take the readings by inserting the probe through the pour spout, but it's not a straight passage through, so I had to unscrew the lid each time. For the first six hours, the temperature would drop by about 10 degrees every two hours (5 degrees per hour). And it was apparent that heat was transferring out through the top (maybe because the lid isn't as insulated as the rest of the body?) because the cap cup was warm to the touch. So after six hours, the temperature dropped to about 174° F. Still hot enough to brew some tea, or coffee from grounds. After the first six hours, the temperature drop seemed to taper off to about 5 degrees every two hours. So at about the 12 hour mark, the temperature was around 156°F. At the 24 hour mark, the temperature was 131°F. I'm guessing that if you use the thermos to store a beverage, like coffee, this should be hot enough (although fast food places serve coffee around 170°F). In case the process of opening the lid to take measurements lets a lot of the heat escape, I also conducted a survey where I took readings at only the 12 and 24 hour mark. In this survey, the 12 hour temp was 159°F and the 24 hour reading was 136°F, so slightly warmer, but not significantly. I guess 131°F after 24 hours would be technically hot. That is, if you put a hot beverage like coffee in there, it would still be pretty hot. But if you use it to store hot water for later use (like I do), you could probably make a cup of hot chocolate or instant coffee. But it seems to be too cold for brewing tea, or brewing coffee from grounds.

Great price and quality.
It is exactly what I wanted. It looks so nice in person and really does keep liquids hot for many hours. The bag that came with it was definitely a nice touch. It’s nice to be able to carry it around without having your hands full. The qualitative is also durable and it seals correctly. Great purchase!

Too good at keeping heat but leaks at times.
Over all a good product. One of my main complaints is that it is too good at being a thermos, my coffee is still burning hot up to 8 hours after I make it which is impressive. The only problem I've had is that when filled to the top it will leak when sealed, I found I have to fill it below the top to keep it from leaking.

The bottle has stopped keeping warm after using for 10 days. Very poor quality.

I myself checked how much time I can keep the temperature fairly high temperature. I use boil water to check.As I realize, even though it is not always at 100° c after 12 hours. I just realized still it is hot enough for a hot coffee. But after 24 hours it is not that much hot during the winter season under 10° c of room temperature. If you pour a hard boiled water at night in the early morning, you will be able to make a hot coffee by using this water in this therm of flask. With my experience I can recommend this bottle for 12 hours of time duration.
