YumSur Coffee Travel Mug Vacuum Insulated Thermal Water Bottle Build-in Drinking Cup Leakproof Stainless Steel Flask for Hot and Cold Drinks (350ML, Black)

I bought this little flask as I wake up during the night and make hot drinks before I can go back to sleep, I also have regular haspital appointments with long waits to see my Doctor.The day this little flask arrived I had such an appointment. I took the flask filled with a cold drink 2 hours later I poured the drink out and found it luke warm. went home made coffee in it, after 3 hours it was luke warm.What a waste of a lovely little flask, it looks so nice, that is why I have given it the sars I have but I could have bought one much cheaper at the local market and it would be far more effective. ( and yes I did have it set correctly.)

I bought the pink one to fit into my handbag when out and about. (I know very girlie) The colour is great and so far it seems to do what it says on the box keeping liquid hot or cold as you wish. Wide neck for putting ice cubes etc in. Being small it is light when filled with liquid. That is a real plus for me. It takes a little under 500ml that again is what I want and I can easily refill out and about at coffee shops etc. Neat little sipper/pouring lid and a cup if you want to drink hot liquids as I would imagine the inside would be hot for lips then. YumSur have thought of everything and all in all a great little flask that ticks all my boxes with design flair as well.

I used this at work and the mouth hole is too wide so if you are not careful, you can pour it all over you. Also the top part is not that easy to clean.

These look really nice and you can drink direct from the flask or pour into the lid/cup which is nice. They don't keep drinks hot for as long as they say but long enough for average use.

This was the biggest glass infuser I could find and it's great! I mostly use it to infuse water with fruit/herbs, but I've done tea a couple of times. Careful of finer teas, as the smaller pieces can get through the strainer, leaving grit in your mouth (I drink straight from the bottle.) Probably better to use teabags than loose leaf tea. Also you need to be careful with the strainer as it sometimes comes loose while you're drinking which can be a mess!Delivered promptly and as described.

At last a really good flask ~ keeps coffee very hot for hours ~ well constructed and easy to clean. Lovely flask for one person as it gives me 3 cups of coffee using the included flask top/cup.

Positives:Slim; relatively sturdy; and rubber base.Negatives:Keeps hot beverages 4-6 hours hot to warm NOT up to 12 hours as described and material does not seem as strong as other alternatives products

Great looking item, the flask bottom half is really sparkly and shiny.Leak proof with a detachable lid to use as a cup.Comes with a plug that you can open to pour liquid from and fully remove for cleaning! Very stylish useful product
