Review on Thermos FOOGO Vacuum Insulated Stainless Steel Food Jar, 10-Ounce, Blue/Yellow - Keep Food Fresh on the Go! by Barbara Freeman

This is a great little thermos, but I have a couple of issues: Pros: - Keeps food hot or cold for 4-5 hours (put thermos in freezer the night before or pour out Put in boiling water for 10 minutes and it will keep a good temperature) - Good size for small children - Stainless steel so it won't stain or rust. Cons: - Narrow opening and it can be difficult to get some groceries that hold 10 ounces, which is a good amount for a child, but if it's for an adult you should probably pack something else. I filled it with spaghetti for my 8 year old daughter and she said it was enough but she ate it all and I'm wondering how long it will be "enough" - the lid/rubber ring is not easy to clean . I use my fingernail to make everything work, but a little nasty. By the way, we have 2, blue and yellow and pink flowers with black bottom and top. I wrote our name on the blue below, but I can't write on the black. However, the pink flower is adorable, looks very grown up, but since they are flowers, they are still cute for a child, and even better, they have no character. UPDATE: We all used them at school last year and I froze things overnight and put them in backpacks the next day. My daughter has a Pack-it lunch box and if the lunch box was frozen the smoothie would still be frozen. My son has an LL Bean lunch box and puts an ice pack in it, he almost freezes during lunch. My daughter is going through a growth spurt and my fear of failure has kicked in. I have to make sure that when I pack spaghetti, I pack an apple or something. They survived without damage or stains. Warning: If you're packing something smelly like eggs, be sure to rinse the lid as soon as possible as the plastic will absorb the smell.
