very useful, here I've added a picture of reeds inspection made one week ago
This avoid you to remove heads, air plenum, and save time, you can't see everythings as in a nice day light, but for the price a useful tool.
for cylinder bore inspection too, you have a little angle mirror.
better to use this on a computeur as the leds put down the cell phone battery very fast, also, you should need to download a specific software to use the borescope, nothing difficult.
You can also use a leak down tester, not so expensive too, and useful also.
