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.

I wanted something that didn’t require use of my cell phone and operated independent of other technology. The picture outs perfect and the side camera is a huge help. I was able to fond the exact location of a leak without tearing out the entire wall. I’m buying one for a relative for Christmas.

For the price it's a great value and works great. The case that it came in really holds it nicely and secure

Purchased as a gift for my husband. Wasn't exactly what he needed, but he says it's well-made and priced well for those jobs where it might come in handy.

Impressed with the build quality. Works with a nice clear picture and comes with a nice hard shell case.

I recommend this camera to any one. Great investment.

The IPS display is bright and high-contrast enough for indoor and outdoor applications without direct sunlight. The color rendering is crisp. The usability is good and easy to understand and the display modes (both lenses, only front lens, only side lens) are easy to set and always well marked on the display. The function of rotating the images on the display is also practical. All in all, good and practical for our applications.

Great video quality, rugged construction and a good user interface. I'm glad I went with this model versus some slightly cheaper options that were available.

Drilled a small hole in my foundation to see where the gap was and placed the camerainto the hole and found out it was the vent system which saved me from going further without knowing where I was drilling into. Saved me alot of time and money.

have used many home construction and auto repair endoscopes over the years and this is by far the best I have used, by far. This offers a very high quality display with HD quality images and videos. With no instructions or information this worked right out of the box, was simple and easy to use and started looking through the camera on the built in display in seconds. After further checking, I was able to connect it to my iPad without any problems and there was no lag between the screen display and the iPad. I took pictures and videos, saved them to the device quickly and easily, and then was able to easily transfer them to my computer for storage or review. I also love how once you have the scope where you want to fish it you can just use the knob with your thumb to adjust the tip to look left/right or up/down (depending on orientation). This avoids the difficulty of pushing/pulling and bending it when you are so close to what you need to see. This device is also well packaged and protected in its case and I have no doubts that this will also be enough for me to pass on to my children.
