This is a great endoscope. When you need an endoscope, you are usually working on something that will be wet, oily or would otherwise destroy a laptop. With this scope, you can quickly see everything with its well lit camera and nice sized screen, and it's all very handy. It eliminates the need for rigging something up with a computer, cords, power supplies, etc. that all ends up being impractical. This scope makes it extremely simple.
The hose is a perfect amount of stiffness & is plenty long enough for any job. The camera can look forward and to either side and all 3 views each have their own lighting. The interface for switching between cameras is very intuitive.
This unit will go toe to toe with much more expensive scopes. Great image quality & resolution. The attachment between the camera hose & the screen unit is very secure and protects both. Price is unbelievable. Don't miss this one.
