some of the products are quite seriously displayed smaller than what's in the freezer, kinda problematic for anyone visually impaired a bit. Not only that but the way the screen changes to advertise stuff is super annoying in a way, you can't tell what brands or exact type of things are in there, forcing you to either wait or open every door to find what you're looking for exactly. It's just attempting to solve a problem that a regular sign above the fridges already solved. Also if the screen wigs out, since tech isn't fullproof, you're now looking at completely opaque glass
