I would give it a go. The quality is supposedly better than a human burger. Some burgers I have had were falling to pieces before I even opened them... How hard is it to line up bread, cheese, beef...
The issue will be the quality of ingredients. Unless they are replenished frequently, they will be flooded with preservatives (more so than they are now).
I was recently in Hawaii. Their "fresh" milk had a shelf life of months! Scary stuff.
