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...

I will have to say I am very happy so far. I am been wanting an inspection scope for some time and I have a condensation drain line issue that I am dealing with and pulled the trigger. It is allowing me to see areas that I previous could not and has been very usual so far. Now, I don't think it will bend through a 90 turn, but the side camera allowed me to view that segment.I think the quality is pretty amazing and the price is right. Not too cheap and not very expensive.I hope this will last for years and I can see myself using for many things. I actually already used it to look in the sump area of my aquarium to find seething that I had dropped in it. I found it and was able to retrieve - just a little bonus.

I have a couple of K&F Concept video inspection cameras and have not been disappointed with any of them. This one is no exception. A highly versatile scope, this standalone device offers excellent image quality in an easy-to-use package. Can be used for all types of inspections. This can be one of those things you didn't know you needed until you had one. From wall cavities, automotive work, gunsmithing — you name it. You will love having one of these on hand.

use this as part of my PPI (Pre-Purchase Inspection) kit. It has a great screen that is very clear. I like the ability to take pictures and videos to avoid hassles. This allowed me to look deep into areas of the car to reveal damage and mechanical issues.

I bought this SMD micro soldering and pcb inspection...look, it’s a sub $100 microscope...and for the money, I didn’t expect it to be so usable! The picture is amazing, and the infinite zoom is awesome. It has the slightest bit of input lag, but after just a day of messing around, I can touch my soldering iron to even the smallest capacitors just looking at the screen. I was expecting it to only be good for PCB inspection, but I am definitely able to solder even the smallest components with this with no Trouble at all. Honestly, I don’t see you finding a more usable scope unless you want to drop an extra 2 or 300 or if you buy a stereo scope. The input lag is almost non existent, but it IS present...however, i can’t imagine anything short of a $400 digital scope really being much better. The the image quality is flawless, the screen, amazing, the zoom will focus clearly at ANY distance. it’s a sub $100 microscope, don’t expect the world...but if your expectations are reasonable, this will far exceed them. buy it, or spend the extra couple hundred to get what you really want because this is the best value for the price range! You won’t find better without dropping quite a bit more.

Fantastic little product. Very helpful in the machine shop.

I have considered buying an inspection scope for years but hesitated due to cost. Finally pulled the trigger on this 16-foot model and, after a couple months of use (spying on termites eating my house inside the walls, confirming the location of electrical and pluming inside walls, even inspecting my ear canals!), am extremely happy with its performance. The picture is super sharp, the dual front and side lenses are highly useful. And the ability to change the light brightness, the tiny size of the probe end and the ability to capture still or video images are all icing on the cake. Some have commented the longer 16-foot probe is a hassle to deal with. This is true to some degree. However It is manageable and I would rather have it available to me if I ever need one that long than save the $10 to $20 and not have it.
