This is almost 5* if it just held a bit more. My husband uses it for work as there's no access to hot food there, and piping hot food is warm by lunchtime if he microwaves it in the flask before he leaves in the morning. I generally put him some of whatever we're having for tea in it and it stores in the fridge over night and then microwaves in it in the morning so it's no hassle which is great. It goes in the dishwasher too. It's particularly good for stews etc but he has used it for roast dinner before and it did work although we had to squash it in! I'm buying another so he can have one in use and one at home for me to fill up.
