“Don't waste your money.
I bought these to try and save money/ make eating at lunch easier for 2 teachers. Well we're 2 weeks in an unless the flask is stuffed full of food the food is stone cold by lunch time. The amount of food that's needed in the flask to keep the food hot is enough for 2 people. So you either have to choose to over eat/ waste food or have cold food if it's the correct size helping. Wished I'd bought cheaper ones from a supermarket where I wouldn't have been so upset with having cold lunch.”
