I thought that until I had a luke warm coffee from one, I would say they aint wot they woz, I bought a small stainless steel flask from Tesco it was on a special offer so for less than a £5 it was throw away, but that was years ago and used it today as it happens. 'Stanley' naa save your money?Back to Stanley mate

Had to look and they do appear very well made:I had the same predicament, when my Aladdin flask broke. I Researched it and bought a Klean kanteen it’s all metal well built tough easy grip coating and as I am out surveying power lines all day it’s my only source of hot water and I even have to put cold in the flask or the thing is too damn hot. Even when I get home and poor any water left over out it’s still hot and that’s even when I’ve put a bit of cold in it.
i even bought there thermal mug which is excellent also, not cheep but great stuff and easy to clean and it keeps it hot.
in my opinion Its best to buy quality and pay the money.
