BorosilVACCUM TREK BOTTLE BLACK, 500ML, BT500BLK102

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

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.

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

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
