Does only the biggest box is keeping the food cold or warm or the little boxes too? For how many hours?

They all kept the food warm or cold. But top container is not as warm or cold as others. And it lasts about 6 hours.

Hello there, it usually takes around 8-10hrs at 30-35C here in EU, which is never the case here. So a Rice cooker(In Keep Warm function) or yogurt maker is required to keep the constant warm function for the duration(Mostly Overnight). The consistency tends to be on liquid side but more viscous/pouring in nature. Keeping it for more than 10 hrs in hot area will make it sour and if your temp is too low, it will take on an unpleasant flavor often associated with spoilt milk.

It's relatively quick between and hour to an hour and a half. I've left food in there as long as 4 hrs and it didn't do any more than warm the food. It really is handy

We have only used these for cold items. Though I have not tried hot items, I can say they keep the cold food cold for at least four hours in my children's school lunch bags. We do not use ice packs.

This was bought as a replacement for unit in Pyrex container hot-cold container. For foods right out of the oven, it usually keeps food warm for about 4 hours. The hot pack is an odd size, 9x12, for kids lunchbox, though.

We had took an 8 hour trip and my milk stayed cold the whole trip. I haven't tried it any longer than that. But from what I remember the pack was still cold by the end of the trip. Hope this is helpful.

They use a frozen baggy, like you would put in your cooler, last about 6 hours and then melts leaving NO CHILL, plus they make it worse by putting this in a silver sealed bubble insulated outer bag, that after the frozen bag melts, it gets hotter inside the insulated bag.........a mess when it's hot outside, since it lays in the UPS truck for at least 6 hours while out for delivery, plus the travel to and from their hub. Best ordered in the fall, winter and early spring.

I would say no more than 6 hours. I packed this for my husband's lunch once.. warmed up the containers with boiling water, as directed, then placed hot foods in it (aruond 7am)... he said it was just "warm" enough to eat at lunch time (12/1pm) but not hot.

I send lunch with our daughter, and there is an ice pack with it. When she gets home, it is not still frozen- or cold for that matter. I pack her lunch at 8:30, and she gets home at 4:00. I am sure it keeps until 12:00, which is all I really need. May I suggest a small Igloo cooler, instead? I can say that it is a great, sturdy product. Easy to clean- no smelly cracks that don't clean well. I am very happy with it, and it will last for years.

Hello! I'm not 100% sure about heat as my sons school asks we not pack up items to be heated but it stays cool for about 2 hours. Longer if we place an ice pack on the exterior lunch box we purchased. Hope this is helpful!

I don't think they would last 9 hours. I use all 4 ice packs with an insulated bag. I even put the bag in the fridge the night before and pack the ice packs before leaving. I've found them still cool after 5 hours, but not enough to help the food.

Ice packs definitely help keep items cold. None are included. I use mine as an adult lunch box, holds plenty

I haven't tried, but the walls of the larger container are filled with a freezing agent, and do keep things cold for the 4 hours before my daughter eats lunch. I would probably go with a standard, stainless steel thermos container if you need to keep something cold for 6 hours.

I put a boiling water as instructed, leave it for 5 minutes, empty, then add HOT food in it at 7 AM. The food is always almost cold there after 3.5 hours. Also, the surface of the container after adding food is pretty warm, so we can't pack it in the same lunch box with yogurt etc. Unfortunately, this product doesn't work for us :-(

The lunch jar we ordered can keep food warm around 6 hours. My daughter brought hot food for lunch during the winter time. She never complain about the "cold food".

Insulation is primarily done by the outermost container. You can mix hot and cold in the smaller containers, but they are not well insulated from each-other.

I load this mini packit with my son's lunch at about 9:30am. When I pick him up at 1:00pm, the bag is still cold. I own the regular sized pack it also; it says cold longer. In fact, I load my daughters lunch in it at 7:30am, and she eats lunch at 11:05. She says parts of the bag are still frozen. I keep all packits in the freezer untill I load them in the morning. Hope this helps!
