Borosil Hydra Trek 500 ml Stainless Steel Water Bottle | Double Wall Vacuum Insulated Flask | 20 Hours Hot and 24 Hours Cold | Bottle for Office, Gym, School, College | 1 Year Warranty, Black

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

I have used this product extensively. Very satisfied with it; the pricing, look and performance

I bought it in 2022, it was holding to the temperature of the water for good amount of time. But from last 1 month it does not hold the temperature of the water for short time only.

The size of the product is adequate and it does not leak due to its rubber seal. The lock is secure and the anti-slip feature ensures stability. The insulation is effective in maintaining the temperature of both hot and cold liquids. The metallic appearance is aesthetically pleasing and the shiny finish adds to its appeal.Professional POV - Considering its elegant appearance, it would be advisable to purchase a jute or readymade cover bag for the item in question.

I have a similar bottle in black of the same brand, however I bought the green one yesterday, which doesn't stay cool at all. It is not the same as the black bottle.Within 1/2 day, the water was at room temperature, whereas the black bottle still had cold water. Both bottles were filled at the same time.

The build quality is really good it keeps water cold and hot for 24 hours and it's a really good bottle the build quality is really heavy and it feels so good and i got an pdf through which i can claimwny warranty anytime within one year and i loved the packaging

Within 6 months bottle starts leaking. Overall bottle was good but it's started liquid leakage from the cap side may be it's seal get damaged but all of sudden why this happened can't understand and it's cap was not available in market bottle was useless after started leakage

Anybody who buys this bottle won't be disappointed !!
