BOROSIL VACCUM TREK BOTTLE BLACK, 500ML, BT500BLK102

It was quite nice for the first few weeks but later it wouldn’t keep water hot long enough

At 20°C the flask could maintain the temperature only for 4-5hrs. At lower temperatures it may cool down much faster.

Purchased June 13 and now it's July 3. We have noticed since July 1st it stopped working. Hot water already very cool after 5 hours of keeping boiled water.

Stopped keeping cold or hot in less than a month and saw some creation of rust in lid area.

Neck of the bottle has rust spots in less than a month don't buy

A few days after purchase, water does not stay hot in the bottle, as it claims 24 hours hot and cold. I bought it for baby bottle and food preparation. there is no return or exchange option. Let us know if there is any possibility to return or exchange

My bottle was keep the water hot for 2 weeks. And just stopped doing it anymore afterwards. Never dropped it. All parts intact. Still

After a few uses with boiled water, the rubber gasket in the lid began to fall out repeatedly. Even after trying to reposition it several times, the bottle quickly lost its heat retention and could only keep liquids warm for about 30 minutes. I hope this information is useful for anyone evaluating the product.

I wanted a water bottle for my bike which has a prospec bottle holder. If you are using normal bottles in a bike, mounting it near the crash guards, the bottle gets heated from the proximity to the engine and thus the water gets heated. The borosil bottle solved this first problem. Even for 8 hour rides, the water inside the bottle is cool and doesn’t heat up. The second problem was most water bottles are of narrow and tall profile. This causes the bottle to be more than half outside the bottle holder making it unstable and also interfering with the indicator lamps when you turn the handles(depending on where you have mounted the holder and type of bike). The borosil bottle is wide (but not too much) and short profile and fits exactly in the holder. And the wide mouth makes it easy to clean. The finish is excellent and feels premium. Also the grip to hold the bottle feels good and does not slip.

Excellent product, Excellent quality very beautiful, value for money, keeps tea, coffee and water hot for 10 hours, easy to carry, lightweight, sturdy, long lasting

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.

Nice product.

Very useful and light to carry , doesn’t leak and easy to use and keep clean .
