This has been around for quite a while. The fact that you haven't seen them being used may speak volumes. This is a special interest item that I doubt the accountants can justify as a cost saver. The classic product in search of a market.
Perhaps someone would spec this if they thought it would help the maintenance man in the future but I don't see bad receptacles as being that big a maintenance problem. Reliability wise your money is better spent in simply using a quality device with screwed in connections.
