Excellent flask
I bought this flask after looking at lots of reviews. My husband is a postman and out in all weathers, so this is ideal for keeping hot drinks warm in the winter between postal deliveries and he will be able to use it on the summer to keep water cold. He certainly gives the flask top marks as it is very durable aswell.

Keeps drinks hot for hours
Great flask, keeps hot drinks hot for hours. It’s a big flask and weighs a fair bit when full, but you get a good 4 or so cups of hot tea from it!

Awesome but watch out for the cup
Amazing flask that does a great job of keeping your drinks hot for ages. Large size, cool design, and very leak-proof. However, despite the bottle being amazing and staying cool to the touch, the same can’t be said for the serving cup, which is less functional. The cup gets very hot to the touch to the point of not being touchable if the drink is super hot, which seems like a bad design flaw. But overall, an amazing flask.

Best flask iv ever had
Best flask ever. I take fishing in the middle of winter. Fill it up at 5am and it's still piping hot when I get home. I even forgot to unpack it once and emptied it in the morning and it was still too hot to drink straight away. 5 stars

Perfect flask
amazing flask two issues is the handle for me it doesnt stay out so if u hold by handle it moves around but other than that it has kept my water hot for teo full days 😂 safe to say its very good at keeping things hot, another issue is the screw in cap doesnt tighten fully wich has caused a leak other than that perfect easy to clean and the full lid is amazing to use as q cup saves me bringing my own
