Literally love this backpack!! Perfect for my Nikon camera while travelling.

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.

This camera works wonderfully! First, it comes with everything pictured...even an extra battery!

The lithium-ion battery charges fully in just 8 hours, allowing you to quickly get back to capturing your thrilling moments.

It allows me to mount m42 mount lenses on my Nikon 1 camera...there is no auto focus with it but it is very easy to get sharp photos...there is no glass in it so the optical quality of the lens used is not affected...this unit easily connects to my nikon one and my m42 lenses...the helios44_3 and the volna9...easy to screw on and off the adapter...the package is a week early arrived than expected and the price was amazing...this was one of the best values I've bought in a long time

This range finder does everything a $399 brand name can and is just as accurate. It has all the features you would ever need and has a rechargeable, built-in lithium battery that seems to last forever.

I wanted to know weather conditions at my other remote house while away. This station works well. Use lithium batteries if you want readings in the cold winter environment.

The product meets my needs to serve as an adapter from a Nikon lens to my Canon camera. The only problem has been that I had to do a lot of research to make sure the lens worked. In the product description they are not too specific. Otherwise perfect and received within 12 hours of ordering
