    Hot ?? May be not !!
  

*by E***D on Reviewed in the United Kingdom on 4 December 2017*

Great for cold drinks but hot stuff only stays hot if you warm you he flask prior to filling.

### ⭐⭐ 2.0 out of 5 stars







  
  
    Very dissatisfied.
  

*by S***R on Reviewed in the United Kingdom on 5 November 2016*

First of all I have discovered that the hot water put into this flask becomes tepid after just 1 hour. Also, it is very small. When it is full it only has enough water in it for just one mug.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars
