Review: Superb, and if it isn't you're using it wrong!! - I spent a good deal of time looking for a food flask, which was easy to use and looked half decent. I was not disappointed with this product at all!! I recommend priming the flask with boiled water before use, this is really just good practice for any flask, when aiming to keep the contents suitably hot!! I can heat my soup/ stew through at 8:00am and by 12/ 1 pm it is still piping hot - and I have total confidence that the heat would last until I got home, if I didn't eat it for my lunch. With this product, use caution when putting the lid on, simply to ensure a tight fit and thus keeping the heat in. Once you have primed for 10-15mins, with the lid on, simply tip the hot water out and pour hot food in immediately, again, to help lock in heat. This flask offers great portion size, filled to the top is a huge amount of soup to eat! (doesn't matter if homemade, because you'll know how much goodness is in there, but wouldn't advise eating a full container of processed food every day, unless you want to pile on the pounds!) All in all, a great, robust and high quality product, which really delivers! I wouldn't hesitate to recommend this to anyone!!
Review: Brilliant flask, with 6 months of use I find it difficult to believe the bad reviews - I decided to trust the majority of reviewers comments and with over 6 months use I cannot be more pleased. After reading some negative reviews I decided to test it properly so after the initial pre warm as you should do with all flasks I filled it with boiling water 98'c, eight hours later I opened the flask and tested 74'c I the left the same water in for another 12 hours and 52'c. I use this for out on the road and prepare food at 0430 and eat around midday and it is still literally steaming hot. Ideal for stews and soups but you have to let it cool or use a bowl. Pasta and rice dishes cool a bit quicker unless you have a lot of sauce and needs experimenting as you need to undercook the rice or pasta and make the sauce watery to allow for it to continue cooking and absorb the water while in the flask, if not the meal can become stodgy or dry.. Once you get the cooking right it is a welcome change from sandwiches and warming on cold days. To the guy who said it leaks and cold in and hour I can only assume you cross threaded the lid which can be done if rushing so yes it will leak and cool quickly as there is no seal created. The neck is a little small for big hands to fit inside to clean but majority of the time it cleans out with a swill under the tap or use your brain and wash brush or sponge and a spoon. It is large enough to fill easily with food and eat from it direct. Before you decide to buy I suggest testing your portion size as some days I need the full litre other days I struggle. Make a typical meal and use a measuring jug or similar to see if the ¾ or ½ litre would suit you better.

## Questions & Answers

**Q: what's the size of the opening? how easy is it to stick your hand/a sponge in to clean the interior?**
A: I could stick my hand in the flask to wash it. My wrist is only 6.5 inches around. A sponge and a washing up brush should quite easily.

**Q: Is it shakeproof?  Can you shake liquid contents without spillage?**
A: I guess so as long as you secure the screw top. I just tried mine for you with water and it's fine. Hope that helps

**Q: Is the flask rated for 8 hours or 24 hours? The title and description do not agree.**
A: if the description is read properly it says 8 hours for hot and 24 hours for cold

**Q: does this really hold a litre?  I need something to keep a soup base in for a market I do. I don't suppose theres a larger than 1 litre size? I'd also like to know how easy it is to clean. Thank you**
A: Sorry this is so late, I have been away. The Can holds 1 liter easily and is very easy to clean. Not sure whether they do bigger ones

### ⭐⭐⭐⭐ Good quality and value for money.
*by H***. on 27 October 2018*

Good size for kids lunches and a great price compared to others on the market. We've been using 2 of these for a couple of months now and overall very impressed. No leaks and food stays hot for several hours if flask is preheated. Only downsides are ; No steam release button - can be difficult to open due to the vacuum particularly with round stainless steel to hold (no grips). Rubber seal is fiddly to replace after washing. All in all very happy with them, good quality and value for money.
