Borosil 850ml Trek 20 Hrs. Hot & 24 Hrs. Cold Stainless Steel Bottle (Black)

This is a very good item, and must buy,Light weight, also keep water cool or worm for more then 24 hrs, best office bottle

Nice

EDIT: Since my flask was out of return date limit, I wrote an email to Borosil customer care email ID on the box. Within a day I got a response and the complaint was attended to via a phone call from Borosil customer care. When I explained the issue I was facing, immediately they decided to give me replacement. Pick-up of the defective item was arranged and a replacement was delivered within 6-7 days of writing the complaint email. 5 stars for the customer support. A rare gesture from any customer care in India!!!! Kudos to you Borosil.I am still not giving 5 stars as even the replacement product is leaking heat through the cap. But the heat retention is much better than the initial product. Overnight the loss in temperature is about 10 degrees. I will still stand by with the performance of Cello Vacu-steel flasks that we already have.Got impressed by the reviews here and bought Borosil vacuum flask. It's waste of money as it's nothing but a steel bottle that can't hold heat at all. I have Cello vacu-steel flasks that can hold heat beyond 12 hours, nearly as hot as when we filled it. In this flask boiling water becomes lukewarm within few hours.The moment you fill anything hot, you can feel the heat on the outer surface of the flask which means that heat dissipation has already started.

It could have been better for the price the size could have been large and the water is not that hot after 12 hours but in the description it is said 24hours idk

I am writing this review after 4 month of use, I strongly recommend not to use borosil products. They have lid issues in all of there products,it may be a water bottle or may be a lunch box. When you are going to claim for warranty they simply told you that lid is not covered under AMC. As a price you need to pay lid cost along with high delivery charges

I recently purchased two of these and have carried these on a trek in subzero temperatures with the flask being kept in the outer mesh of my rucksack. It retained the hot water content inside easily for more than 5-6 hours.I've been also using the flask as my daily hot-water-bottle while working, and the hot water in it easily stays hot for 5-6 hours. Difficult to test it for a longer period of time because one usually ends up drinking all the water by that time :)Is extremely rugged as had the bottle fall out of my sack a few times. It did get a few dents and scratches, but so would anything if it hit a hard piece of rock.The bottle is decently heavy and feels well built. The strap and the plastic ring to which it is attached is also pretty strong and did not have any loose stitching threads come off the strap. It was easily able to take the weight of the bottle whenever it was hung on the sack while walking.The bottle cap makes a very tight seal and there was no leaking. There has been no smell coming from the bottle till now. Even though the bottle cap is made of plastic, the way the bottle threads are designed , there is almost 0 contact with any plastic elements.If there is a negative, it is that the outside of the bottle, being made of metal, becomes very cold or very hot (depending on the weather) if kept outside and exposed to the elements. Would be good if a cloth sleeve is provided/bought and put on the flask. This would help in holding the flask in adverse conditions and also act as a layer of protection from any scratches (and also make less noise) in case of a fall on any hard surfaces

Best purchase

Was ordering again for one of my family members as the quality is pretty good,along with water staying cold for about 6 to 7 hoursBut due to a big mistake by the delievery guy who just threw the package over our gate which is like 10 feet tall it now has a dent at the bottom, a complete fault on Amazon's side. Otherwise the bottle is in perfect condition and is keeping cold water cold for now

Durable product

Excellent product

I like the sturdiness of this bottle. It took a few times to get the right amount of torque to close the top. Too much torque pinched the gasket and I would have to reposition the gasket. It keeps hot beverages hot for hours, and cold beverages cold without any condensation build up.

They should be trusted you
