Daxiongmao Endoscope Camera with Light

I've used one before it saved me an unnecessary engine tear down and that not only saves time but money also let alone the amount of work for a tear down is a lot I am a mechanic rebuilt my first engine for my first car at 15 my close family all drag raced for years we did all of our own work this tool would have been a god send it could save you from a major tear down since you could see inside the motor BEFORE tearing it down too far I LOVE MINE
