Borosil CafeTime Mug, Stainless Steel Insulated Travel Mug, Double Wall Vacuum Insulation, for Carrying Tea, Coffee, Soup, 400 ml, Black

Good product, worth it for me!!Why did you pick this product vs others?:Good brand name and rating.Functionality:Good for keeping cold items cold.Value for money:Worth it.

This bottle is supposed to keep liquids cold for 13 hours, which means that the liquid should be at the same temperature for 13 hours.Started by filling the bottle with refrigerated water and four large ice cubes.Ice cubes melt within 3 hours.Water is close to the refrigerated temperature for another 3 hours.After that, the water temperature rises to cool.The double wall needs to be thicker for a 13-hour cold retention.

Not a great product, couldn’t keep the drink hot for longer duration

While it does insulate beverages and keep them warm/cold (Although I have not tested it to the limit of the claimed time), everything else about this product is absolutely awful.The lid is excessively overengineered but still sucks. The button to open/close it is flimsy and looks like it will break within a few weeks. The sipper point is badly shaped and has terrible placement, almost guaranteeing a minor spill every time you take a sip. The lid also retains liquid inside it even if it is shut and is an absolute wonderland for breeding bacteria. This water retention makes it impossible to clean properly and will lead to you drinking a cocktail of fungus and other delightful microbes within a few weeks of daily usage. Expected much better from a brand like borosil, but this is an absolutely brain dead design that is more focused on aesthetics than actual functionality. One of the worst products I have ordered this year. Avoid at all costs. I am looking for a better replacement and will edit this review if one is found.

I would rate this 4.5. Looks elegant and classy. Does it job well. Form factor is slim and easily fits anywhere. One small issue if you use eyeglasses. The coffee drops on the flask cap tends to touch your eyeglasses while drinking, as it protrudes a bit (probably helps in making it leak-proof). However this is not a let down. Definitely recommend this

I use this for filter coffee. If you put boiling hot liquid like 100⁰C it'll stay hot for like 4-5 hours or something. And at 90-95⁰C it'll stay hot for similar time and maybe a little longer. See i noticed if you put the 100⁰C water it'll come to 93-95⁰ in like 3.5 hours so not that great but in my case I open the lid in between it'll depends but it'll stay hot for 3 hours bare minimum no matter what you'll do. The mouth is big so it's easy for cleaning, I dropped it once but there's, no such damage and all. I like it's matte finish over flossy any day it's light weight.

Premium look and totally worth the price. I have not tested this since it is a gift but I do own borosil coffeemaker mocha 300 ml, which is totally worth the price. So I know this gift will be well used.

Yes it's easy to clean. I like it. It's leak proof and weight also manageable.
