Review on DERABY Insulated Casserole Containers for Commercial Use by Heather Green

The quality of this delivery bag is very good but it doesn't keep my food warm. I tried reheating 80 tacos for breakfast. They were foil wrapped and placed on a foil lined/wrapped tray. They were only in the bag 1 hour but barely warm when I got to my destination. This can keep food colder rather than warmer. I haven't tried this option. It would be nice to have a shoulder strap on the bag. Unfortunately I had to send the bag back to Revane. I give it 4 stars for its quality and not for the insulation. The bag is well made.
