Best Heated Delivery Bags?

Anyone have a recommendation for the best heated delivery bags? And what is the process of using them?

When I used them at my first pizzeria years ago I had them all plugged in on a shelf by the door and the Routing Manager would put 1-3 orders in each bag for the next driver and that driver would bring back his bag from his previous dels, unplug the bag with the 1-3 orders and plug his returning bag in that spot and so on.

Here are the 2 top sites for heated delivery bags.

I can’t really comment on the usage process but I’d say that the description you provided pretty much sums it up!
