### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Amazing!!!
  

*by A***R on Reviewed in the United Kingdom on 16 February 2024*

This flask is a MUST have!! I had bought the Tommee tippee "go prep" bottles to make my babies milk when out and about so it's vital the hot flask holds it temperature but it didn't hold for more than an hour.  After searching for a decent flask I found this one and the reviews seemed good so gave it a go.  It is brilliant!! It stays hot until the next day!! And holds alot of water too, highly recommended 👌

    Keeps Very Hot
  

*by A***N on Reviewed in the United Kingdom on 11 September 2023*

This flask is brilliant for keeping boiling water hot for over 24 hours. Not tried it with coffee & milk, so can't say how long it would stay boiling hot for but I'm hoping it will live up to expectations of my white coffee staying hot. Not the best for cleaning but a bottle brush of some sort will help with that. My only gripe with this flask is the instructions (well I'm assuming they were instructions, could of been a cheque for a thousand pound for all I knew lol) are put inside the actual flask and its virtually impossible to get them out, without chopsticks,  alien finger or long tweezers. I had to boil mine out, let it disintegrate into  little bits before it would come out. So maybe they should be put in the lid or held round the flask with an elastic band anything but putting them in the actual flask.  Overall its a good thermos flask and would no doubt keep ice water cold for over a day at least. Not tried it but I'm assuming it would.
