FAPPEN Double Walled Vacuum Flask Thermo, 450ml Stainless Steel Insulated Water Bottle, Flask for Hot and Cold Drinks, Travel Coffee Mug, Sports Water Bottle, Drinks Cup (White)

We have been struggling to find a non-leaking flask that keeps drinks hot for as long as possible and these flasks seem to tick those boxes. They even fit in the cup holders of the car. We bought 2 to test and then 2 more since we were so impressed. The drink stays very hot for a couple of hours and then very slowly cools, so you need to be cautious when using it soon after making. We would highly recommend them.My only problem, very minor, is that when I pour the drink into my mouth, the lid wants to fall on my nose. A very minor detail and it doesn’t stop us highly rating these flasks.

Got this coming put of hospital as only on fluids. Kept them hot for a good 8 to 12 hours. Thought it was brilliant but it didnt last long. It only remains hot for a short time. The outside gets hot while inside cools down. Odd but thats what happens. Great for taking on trips, holds easy 2 to 3 cups but sadly, stopped working. I was so impressed bought another but that too is on its way out.

It has a good insulation and is comfortable .

Keeps my cold drinks cold for at least an hour, but if you used it for strong teas, the aftertaste will be there only the next time you drink something different in it.

It keeps the coffee hot all day. Is very handy to put in your bag.
