Works well:Good price

This is a great unit. Found and fixed my problem. Instructions could be a bit more helpful though. Easy to use!

I purchased this after reading the reviews and also because I needed a long camera flex scope. I had to travel to CT from NC to survey a trimaran that was interested in purchasing and did indeed purchase. I specifically needed to inspect the stainless chainplates that secure the mast shrouds. This was a racing rig and this securement is super critical and needs to be well inspected. Of course they were inaccessible expect in one had a camera endoscope type device, which I did. I hadn't even tested the Tesslong out before the flight but I did charge it up. I was super simple to use. The cable is indexed for proper orientation. Attach and turn it on and put it to work ! Super clear images well lit also ! I high recommend for any type of mechanical inspection. You will need a micro sd adapter card for a few dollars to view your saved photos on a computer. Plastic instrument doesn't seem to be made of high impact plastic or rubber coated plastic so I would handle it with care. The case is high impact plastic and the instrument is well protected in the case. Battery life seemed well within what I need for the days work.

Great price for a very useful tool to have. Works very well in the engine bay and even just using around the house or losing an item in tight spaces. Has several light brightness settings or no light. Able to take pictures and video. Screen is the right size to hold in one hand while scoping with the other hand. Battery lasts quite a while and seems like I only charge once a month or every other month.

Awesome product!! I’m in the inspection business and this camera has very good lighting and picture quality is great.

As an HVAC technician I can honestly say that this tool has been one of my best investments i have ever purchased at such a low cost. I own a $1300 combustion analyzer yet this $150 tool helps me make more money in the field. I primarily use this camera to inspect heat exchangers. I have purchased 6 cameras within the last 10 years including other K&F Concept models and this camera beats them all by a land slide! The camera cable itself has durable Material and will not get cut by metal. The cable is also very flexible yet sturdy enough to bend in the position you want it to take a proper picture. The picture quality is literally unbelievable compared to what iv used in the past. You can clearly identify things that are less than 1/4” long and a millimeter thin. Make sure you adjust the date before sending pictures over to customers though! You’ll get screwed! Lol. But yes if you do hvac and want to do a thorough check in heat exchangers this is your tool!

works It works perfectly

I like this borescope, it's a handy tool to have when you get in a tight spot.

I have a 2003 Camry 2.4L engine with a P0420 OBD-II Trouble Code. I was told to buy new catalytic converters. With a price tag of $2,500 for new converters, it made sense to do my own inspection and work-around. There are many catalytic cleaners on the market, but how do I know if the treatment I used worked? I needed to get some pictures inside the Catalytic converters, and they had to be bright and clear. After studying every review of the K&F Concept , it looked like the best bang for the buck. As I treated my catalytic converters, the pictures revealed my success along the way. I saved a ton of money with the . It took about 15 minutes to figure out the buttons and what they do. It's all in the settings and MODE switch. The OK button takes you through where you need to go in each MODE search. It's as simple as that. I love the fact that the screen tilts on the handle. The tilt comes in very handy. As for the quality of the machine itself, there is nothing negative to say. The screen is large and the images are crisp and sharp. I love the camera cable. It is heavy duty and strong. It feels very professional while using it. The camera itself is tiny enough, about the size of a pencil. In fact, I just ordered the 3.3 foot
Borescope-Inspection Camera Accessory that goes with the . It's Waterproof. It comes with a Hook & Magnet Mirror. The 3.3 foot camera cable completes the for me. I found caps to cover the two ends on the 16 foot cable and will hang it in my garage. I plan to use the 16 foot cable for my home inspections. Then I will put the 3.3 foot cable in the beautiful case the comes in. I will use the 3.3 foot cable more often for auto repairs, etc. I would recommend the K&F Concept without any reservations. I was not paid for this review. Nor was I asked to make one. It all comes from the love I have for this device. This camera is a great tool to have when you need it. It can save me a lot of money when inspecting things around the house. Being able to look inside of things without taking them apart is a dream come true for me.

I am an HVAC tech I use this camera during my furnace safety inspections , literally pays for itself when you find a cracked heat exchanger. I would say this is an essential tool if u work on furnaces. Very clear picture quality & quality built battery life is solid. really only con is that the camera is too long for how I use it but that could be a pro for someone else. If you do furnace heat exchanger inspections this is a must buy !
