I bought this about 5 months ago. I used it several times and the camera cable broke from bending it a tight 90 deg. I sent it in for warranty and I got a whole new unit. This is new, never used.
It is not something I find myself using a lot. If I find an engine low on compression I tear it down, no need really to look inside beforehand. It does have the smallest camera that does fit down diesel injector holes. http://www.autel.us/Products/mv400.htm
I am looking to sell it or trade. I am always looking for quality fishing gear or gun stuff. I bought this off a tool truck and after researching the price now, I got the hose. Amazon has it for 161$ call/text 717-813-5846
