Review on LuenHego Insulated Food Jar 26 oz - Wide Mouth Thermos Stainless Steel Lunch Container - Leak Proof Vacuum Flask with Folding Spoon - Royal Blue by Cassie Zingone

When I placed the order I had planned that my daughter would use it when she goes to kindergarten but when I received the order I know that it will be too big for her. So I'll hand it over to my husband. I pour hot water at 9am, when I open it at 2pm it's still HOT, then I open it again at 6pm it's still HOT. So if you use it for lunch at work, it's perfect. I even try turning it upside down for an hour and no leaks yet. One thing to pay attention to: when you remove the spoon from the top, the temperature of the spoon can also be very hot. Overall this is a great size for adults and can hold the temperature for a very long time. If they are a smaller size for a child, that's perfect!
