This item keeps the food hot and or cold for a while, the temps don't drop too much but the negative is that the locking mechanisms are plastic and break very easily and equippers.com no longer sells the metal ones they used to come on the box. I also noticed that the hinges let the door come off by pulling up that comes in handy when you are cleaning but when you are stacking them you have to hold on to the door in order to not get your fingers pinched and the door starts to slide off and so it makes it very difficult to stack when trying to load. They really need to change back to the old style or the style of cambro hinges and locks. It is frustrating to spend 200.00 on something that you have to "fix" to begin with by going on a different website to find the metal locks! I am currently looking for a new website that sells them together.
