Yes...in fact it does a much better job than the Vividia VA-400, even though it doesn't have the articulating head.
The semi-rigid design let's you fold it back on itself before inserting into plug well. It has no problem going in cylinder this way because it's only 5mm in diameter, and folds to just over 10mm dia. May be a bit snug if you have 14mm adapters in though.
I also found that the focal length is much better than the VA-400, and the resolution far superior. It also has a side camera for viewing cylinder walls. All around you can see things much better in your cylinders than a VA-400.
I'll take some value footage and post the next time I'm at hanger.
