Eiffel 1000 Vacuum Insulated Thermos Flask with Strap to Carry, 910 ml, Long Hours Hot & Cold Water Bottle for Office, Hiking, Trekking, Travel, Black

Initially, I received a defective product. It couldn't retain the temperature properly, and the hot water became cold within about 4 hours, so I requested a replacement. The replacement product is completely different and works perfectly. It keeps water hot for around **48 hours**, just as claimed. The outer plastic body is good, and the insulation performance is excellent. One thing to keep in mind is that the inner insulated bottle is made of **glass**, so it should be handled carefully to avoid breakage. Apart from that, I am very happy with the replacement and its performance. If you receive a defective piece, I recommend requesting a replacement instead of returning it immediately.

Good product, no leakage, bought at 70% discount price.

Good thermo flask. Portable But problem is use it handle with care because it's inner is made up of glass which can be break if use roughly. No leakage. But cover cap is low in quality which is not tighten properly. Due to this some heat might release out. But keeping same temperature for nearly 24 to 32 hour , which is good in this price range. Ease of cleaning is not so good by hand . So use bottle cleaner brush for it. Odor is not coming but you have to dry properly for 2 hour after use for better odor control.

Mentioned it fails to retain temperature I bought the Milton Eiffel 1000 for my daily commute. The build, strap, lid and seals are all well made and it’s leakproof — no visible damage or defects. However, it fails to retain temperature: hot water cools to lukewarm within a few hours and cold drinks warm up noticeably sooner than other vacuum flasks I’ve used. If long-term insulation (6+ hours) is important, this unit didn’t meet my expectations. Good design and portability, but consider alternatives or contact Milton support/warranty for a replacement.

Kept the same boiling temperature for more than 24 hrs. Wonderful product and cute

Medium quality heat did not stand for even one night its waste for me

Excellent product with good looking

Cap Cover is very weak and open on small pressure. Not good for traveling
