Milton Eco-Flip Flask 1 Litre (1000 ml) Stainless Steel Water Bottle – Double-Walled Vacuum Insulated to Keep Drinks Hot or Cold for 24 Hours, Leak-Proof, Ideal for Office, Gym & School – Black

The flask is well made , the nozzle modification looks strong . It keeps cold drinks cold for a good while and hot too . Obviously as you drink from it the temperature will go up , or down, depending . The coating on the exterior of the flask can be a little slippery so make sure of a firm grip , Good flask .

Keeps the heat for around 12 hours. The cup is a great size. More expensive than I expected but I'm glad I have it. It's a shame it didn't come with a cleaner, as your hand can't fit through to clean it.

Nice pruduct and wprks well

Good product, using for couple of months, my hot water remains hot for 12 hours

product was exactly what we wanted at a good price

Good product

Very good product

The worst product I ever purchased from them, I brought a same product 8 years back and still it's good, considering that I purchased with much expectation but it's not even hold hot like a normal water bottle, after 1 or 2 hours when I open the flask I used to think whether it was kept in flask or refrigerator, that's the situation. Utter flop, waste of money 🤑. Even though it's a flask we cannot touch on it when hot water is there in it. Means it has no insulation. Is there any solution like exchange or something?
