Borosil Hydra Travelsmart 260 ml Stainless Steel Water Bottle | Double Wall Vacuum Insulated Flask | 8 Hours Hot & 10 Hours Cold | Leakproof, BPA Free | 1 Year Warranty, Rose Gold

The quality seemed good when bought on September 18, 2023. Writing review after the use for 35 days, coffee doesn't stay hot for 15 minutes also. Not able to understand what to do

One and half month k regular use me hi iski heating power finish hogayi .. tea garm ni rehti blki bottle bahar se heat krne lgi . Ab ise cold water k liye use kr rhi hu but same pani under normal ho jata h or bottle bahar se cold feel hoti h. There is some manufacturing defect. No need to buy. Total wastage of money. It's better to purchase from offline mode. Atleast guarantee warranty k sath to milegi or replacement option b rahega.

This product of borosil is excellent...water remains cold for about 24 hours....steel quality is superb....design is beautiful...convenient to carry...very gud product of borosil

260 ml is the perfect size for two cups of tea, so I decided to test this out, as well as another one of exactly the same volume by Milton, and this flask emerged the clear winner. I tested out both flasks by pre-heating them by filling each one with boiling water for five minutes, and then replacing that with hot tea.I used an infrared thermometer to check the temperature. Here's what I found.Temperature of tea poured into both flasks: 89°C.Temperature on pouring out 120 ml after 1 hour: this flask 85°C, other flask 78°C.Temperature on pouring out the rest after 4 hours: this flask: 73°C, other flask 48°C.Most people prefer their hot tea to be around 63°C, so this flask's temperature retention is acceptable. That said, the powder coat paint finish is not great, and the glossy plastic base and lid is bound to pick up scratches and look unsightly as the paint peels. In contrast, the Milton flask had a far superior and likely more durable paint finish, but it retained heat poorly compared to this flask.Pro tip: Heat leaks out through the lid, so cut out a piece of polyurethane foam and fill it inside the hollow container / pill box inside the lid. Make sure the foam is a slightly snug fit with no gaps, but not tightly compressed (else it won't work). Foam is an excellent insulator, so it will reduce heat loss through the lid marginally. And of course, be sure to pre-heat the flask by keeping it filled with hot water for five minutes prior to your actual beverage.

This bottle looks so classy and elegant..Loved it

Cannot keep beverages hot for at least 2 hours. Waste of money

Heat withstand is good and superb product and brand

The flask looked beautiful and I took it outstation the day I received it. Only later next day I noticed that the metal ring at the bottom was damaged. The metal seems to be rusting and damaged in a brand new flask! Maybe I didn't check too carefully as I trusted the Borosil name.Unfortunately, as I have left town and don't have the original box I am unable to return it.So suggest you check the product thoroughly, especially at the bottom.Update on 8 Sept, 5 days after using: the inner white ring has got stuck and detached from the upper part. And is not getting re attached. This makes the product unusable. The product design needs to be re looked at by Borosil.Update on 15 Oct: I somehow ee attached the cap and made it work. But today flask has suddenly started heating up. I clean it just with water and a little detergent powder and a light bottle brush occasionally. Obviously the vacuum seal is compromised.I wish the company would replace this piece and instil confidence in me, a customer of iver 30 years.
