I does what it states it does.
on January 29, 2012
The camera's focus is crispest at 2 to 6 inches. The 4 led lights provide enough light to see the walls of 4 inch to 6 inch ducts, but not much more. I used a bunge cord, and tied the camera to the bush of my 20 ft flexible duct cleaning rod. As others have stated.
I found to instructions, written in broken english, to be adequate. There really is not much to the instructions. Plug into a USB port, insert the disk, and run the camera software.
I found the supplied software to be minimalistic, but good enough to see what the camera is seeing. The software only records in Microsoft AVI format.
I had no trouble dimming the LEDs, however I am unsure why one would ever do so. Full brightness is good enough to see about 5 inches, and not much more.
This is a simple set of LEDs and camera on the end of a 30ft flexible wire that plugs into a USB port. I would recommend it to someone looking for a cheap way to look inside ducts a few times, who alreay has a flexible duct cleaning rod of some length. It is not a professional tool.
