It is a very good piece of equipment. This is the second device, I had a similar one before which I unfortunately destroyed (my fault).
It's almost the same, only this one has a slightly sturdier housing and a stepless LED brightness control.
The resolution is really top notch. As an example, with a bank bill, as it has a lot of small details.
I have the camera to make the job easier. The semi-rigid cable makes the camera easier to guide than cheaper USB cameras with a flexible cable.

Positive points:
- Aukkutausch possible with a little skill.
- Continuous brightness adjustment possible
- Good image quality
- SD card included
- Video recording possible
- dual camera view
- useful settings in the menu
- Rechargeable lithium battery via powerbank

neutral:
- the charging port and SD port could still be protected with a rubber cover, as surely the device is often used in dirty and wet environments.

The cable is 5m long, but I can't imagine I'll need the full 5m, let alone be able to push it that far, especially on various curves I think it will be a bit difficult, anyone who has pulled cables knows what I'm talking about. The case has rubber caps on the sides, so the unit could survive a drop or two.

The case can be easily opened with a small Phillips screwdriver, and the 18650 lithium-ion cell can be easily replaced if the battery breaks at some point, or you can replace the cell with a higher capacity cell.

So versatile. The monitor gives a really good, clear picture. The camera can really see almost everything. Super controllable on the monitor. Photos and videos can be taken. All of this can be easily stowed away in a shockproof case. Really good and a clear buy recommendation.

I have tested the endoscope extensively. the enduscop has saved the need to remove parts in the automotive sector. I didn't expect to get so much quality for the price.

I've tested quite a few endoscope cameras, all of which were junk. With this camera you get a reasonable quality that you can do something with for a relatively low price. In addition, there is the very chic and nice hard case and the accessories. I highly recommend this product!

The two cameras allow quick and easy switching between front and side views.

The image quality is very good. I use the part more often and cylinders, for example, are easy to endoscopy.....

Super picture performance and also save the pictures taken.

We use the camera in a workshop to look at the cylinders. The quality is perfect, really can't imagine what was.

This endoscope is the best I've used, even compared to the big mainstream brands that have a high price. The images are clear. It's easy to use. It has everything you need in the box.

I am happy.
