If you're looking for a good all round inspection camera this is it....
I purchased this with specific task in mind:
1. Plumbing inspection and leak detection especially when the drain is clogged...
2. Automotive and light duty Truck repair - used it to do visual inspection inside cylinders on diesel engine valve, cylinder walls and piston.. I used it to locate hidden bolts while changing out cam driven distributor on 1994 Toyota Camry..
3. Home HVAC inspection on evaporator, condenser, and supply side air registers.

I am retired and no I am not a professional.. just like fixing things and the K&F Concept Inspection Camera is soooo much better than using an inspection mirror and a flash light....plus you don't have to climb over or under things to do inspections....My wife uses it to find things that she has dropped behind the washing machine, dryer or the stove...

What an incredible battery! Whether it's to power your camera... a small LED light (I used it on a USB-C folding panel, nickel) or any accessory on a shoot (of course it charges a phone) it works really well! K&F becomes a real reference in this field

Quality best inspection camera I ever own.

I use it for inspection of sewer pipes and have seen the image very well

This is the best camera to use outside that I have found for a low price . It has a very solid metal case and weather proof so heavy rains or snows will not be a problem. The video quality is excellent . The infrared LED's light up a lot more area at night than I would have ever imagined. Since I am powering this remotely with a solar setup I like the fact that I can turn the LED's off using a setting in the app to conserve energy during low light times in winter. I was truly surprised by the quality of this camera - there are lots of other brands for indoors that are pretty good but nothing compares to this truly outdoor weather proof camera at this price. And yes it is easy to adjust and install .

Article was delivered very quickly and neatly, article then times taken in inspection. Was actually already mounted everything, memory card was inserted, endoscope already mounted and accessories such as Imbussschllüssel small spare screw in a small plastic bag available.
Switched on, battery and was almost to good 100 percent loaded----- thus immediately ready for use, endoscope actually very rigid and the function of the LEDs as it advertised or advertised. The side LEDs can only be activated as well as the camera switching to the left / right view, by pressing the small push button on the endoscope (USB port on the camera). Screen provided with protective film and everything in an associated case well and safely to store or protect available.
Image quality for close-ups acceptable to good, editing options but to be qualitatively better .... there you can about an image editing program still rausholt so some (but is not a point of criticism for me, just a note) ....for the quick snapshot, inspection / examination or short video sequences but quite sufficient.
USB - connection to the camera with a small screw fixed, has its reason because the cable is a little rigid, it protects the connection in the camera from accidental loosening or breakage. The small support foot, which can be attached to the camera, is well-intentioned but somehow not mature, unless you no longer move the endoscope cable because otherwise the camera actually does what it wants.....slides back and forth or falls down if necessary.
Settings of the camera such as date, time, language, etc. quickly and intuitively adjustable. Manual available .....
You should take the time to check all functions and familiarize yourself with the camera. If questions arise, the customer service provides very fast and friendly support in a short time .....Klasse
Should the quality and customer service remain so, which I hope, the camera is for me a clear buy recommendation.

I purchased the K&F Concept Inspection Camera 8MM, Industrial Endoscope-Borescope, 16.4 ft Cable for my husband to diagnose problems inside a wall in our home and view difficult to reach gutters on our home. However, he has not really used it since he unwrapped it on his birthday:)I've been using it for all sorts of things...looking...inside a wall,underneath the refrigerator,inside the vacuum hose for a clog,inside the dryer vent,down a drain that was clogged,inside our toilet bowl,underneath beds,inside my mouth for a molar that was cracked (easier to see holding the device screen up to a mirror so the image is not reversed),behind some heavy furniture,underneath the hood of my car,underneath my car, etc!!In short, it has been the most useful birthday present I ever purchased for my husband! :)

I have tried numerous other inspection cameras, phone attachments, etc... None of them can hold a candle to this inspection camera!I used it to inspect the piston wash on piston tops and cylinder cross hatch marks inside the bores and it works fantastic for this.It's a little difficult at first to get the scope pointed the way you want, but with a little practice and pre-shaping before inserting it into the bore you can look exactly where you want.There's also a 90 degree side camera that helps look at cross hatches in the bores too...I'm very pleased with this camera...I have a lot of different vehicles, motorcycles, snowmobiles, etc that I'm always needing to inspect and this works fantastic.The picture resolution is excellent, stays focused too.Seriously, spend the money, its worth it for what you're getting.
