Borosil Hydra Trek 850 ml Stainless Steel Water Bottle | Double Wall Vacuum Insulated Flask, Green | 20 Hours Hot & 24 Hours Cold | Ideal for Personal & Corporate Gifting | 1 Year Warranty

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

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'm using this bottle from 3-4 months, it's very good and decent bottle, it's good for office use. The Cold water will remain cold max 7-8 hours only, according to the price this bottle is expensive from other brand.The durability is good and it's easy and comfort to carry, no need to clean this bottle from hard sponge or hard scrub it's easy to clean.

Very good product

Worst product with in 6 months hot water is not staying less than 1 hour

Compact, light and sleek design

Excellent build, but poor design. The steel cap gets quite hot and loses a lot of heat from the exposed steel top. After 4-5 hours boiling hot water is barely hot. Likely to perform worse in winter.

high quality - value for money - durability - can hold temperature upto a day or more. will recommend.
