Any pirep on AVPlugs?

Saw the company is having a 60% off Christmas sale on their plugs. If not familiar with them, these are adapters that allow the use of automotive Iridium finewire plugs in place of aviation plugs for use w/ magnetos. A set of 4 is now $250 instead of $550. Was interested but looking for other opinions before proceeding.... avplug.com
