“A nice travel mug with double insulation. It keeps my drink warm for about 1.5 hours, if you want it to be warm for longer then maybe try the stainless steel range but for me I couldn't taste metal.
Another good thing is that when you screw the lid tight there is no spillage whatsoever.
The flask has a nice lid where you can drink anywhere, which is handy when you are thirsty at night. The bottom is made of silicon so is anti-slip. Have been using this instead of mugs all weak and so far so good!”
