Really great part. It's the second device, before that I had a similar one which I unfortunately broke (my fault).
It's almost the same, only this one has a slightly more robust housing and stepless LED brightness control.
The resolution is really great. As an example with a banknote, because it has many small details.
I have the camera to make work easier. The camera can be guided better through the semi-rigid cable than the cheaper USB cameras with the flexible cable.

Positive points:
- battery exchange possible with a bit of skill
- infinitely variable brightness adjustment possible
- good picture quality
- SD card included
- video recording possible
- dual camera view
- useful settings in the menu
- lithium battery can be charged via power bank

neutral:
- the charging port and the SD port could still be protected with a rubber cap, since the device is certainly often used in a dirty, dusty, damp environment.

The cable is 5m long, but I can't imagine ever needing the whole 5m, let alone being able to push it that far, especially around several curves I think this will be a bit difficult for anyone who has ever pulled in cables know what i'm talking about. The case has rubber plugs on the side, so the device could survive one or the other higher fall.

The case opens easily with a small Phillips screwdriver, and the 18650 lithium-ion cell can be easily replaced should the battery fail, or the cell can be replaced with another with a higher capacity.
