Damoc is the principle and pretty much only competitor to Cooler Screens, in the cooler-with-a-screen space. I hesitate to endorse any implementation of this as a good idea, but if you accept the premise as Cooler Screens themselves articulate it, it's pretty obvious that Damoc has come up with a far better product.

I suspect that's part of the air of desperation in the Cooler Screens/Walgreens relationship. Cooler Screens doesn't actually have leadership on the technology so they need to hang on to their major customers to appear to be the mature, ready for business option.
