Used the inspection scope this past weekend. Put it into the black tank and was able look around and determined that the blank tank will need to be replaced. One thing I don't like about it is that you tend to hit the on/off button while holding it and manipulating the view. Other than that, can't complain, has been very handy. The 12v
screw gun that comes with it is really great. Everytime I peer into a nook or cranny of my AS I keep expecting to see something looking back at me !!!
I would reccomend this tool.
