The day it arrived I used it to look inside a motor to check condition of cylinder walls and top of pistons of an old car I own. Picture quality was very good, it was a little tough to turn the cable to view all around inside combustion chamber, side camera was helpful in that respect though, a nice feature. Unit came with a hook and magnet, and one other attachment, but they do not fit on end of the cable at camera lens, so it is useless, I have to order the set made specifically for model I bought. Unit is simple to use, and there are many reviews on YouTube showing how it functions. So far so good with this set up, though time will tell.

I had an issue with the head unit over a year after I purchased the product. I contacted the seller. They sent me a new head unit for free the next day with no questions asked. They didn't even ask me to ship the old one back. Very happy with the customer service and very happy with the camera. It has really been helpful in so many situations.

Used it to track flow of dye in pool lines. Was afraid this would not work well in water but worked great and took clear view so we could track flow of dye into the lines to help us determine how far in the pipe the crack was. Very handy tool!

Ordered this sometime around Oct 2021 and the camera ended up shorting out sometime around June/July. I contacted the seller and they sent a new one right away. Camera is great and has definitely paid for itself. Customer service was fast and easy, definitely recommend buying this product from this seller

I needed an endoscope camera because I wanted to see where power cables were running under our suspended ceiling. That's when the Teslong camera came in handy.

The device from Teslong comes in a sturdy hard plastic case. The package includes the handheld with a 4.3" display, a 5 meter waterproof camera tube (with triple camera), a device stand, USB-C data cable, various attachments for the camera, a 32GB micro SD card, a mini-inbus key and a manual (incl. German language).

The camera is securely attached to the handheld, but can be removed using the mini-inbus key. The connection of the camera hose then turns out to be a USB-C cable (whether this can also be used on other devices like this, I could not check now). I was immediately enthusiastic about the model, since it comes with a self-sufficient handheld. I already had various endoscope cameras. However, they always had to be operated via smartphone or notebook using an app (sometimes not entirely trustworthy). Depending on the Android or iOS version, you couldn't get the cameras to work at all, and handling a notebook in a tight corner isn't that easy either. Therefore, a huge plus point for the camera from Teslong.

The battery was already pre-charged and the SD card was already inserted and pre-formatted. So we could start right away. The camera hose is relatively rigid, so you can also drive through longer pipes or hard-to-reach areas. The rigidity is to my liking. In the past, the cables were relatively thin and usually snapped off and got wedged right after being inserted into a constriction or pipe.

The device itself feels good in the hand and you can act well with the device. The buttons are large enough to operate the device with one hand and guide the camera with the other. During the test, I stood on a ladder under the ceiling and inserted the camera through a small opening in the ceiling lamp (diameter of the camera housing approx. 8.5mm). Everything is clearly visible on the display and the pictures taken correspond to the display. The built-in LEDs are top and illuminate even a stock dark area well. The camera can be switched 3-fold (to the front, to the left and to the right). Thus, an area can be viewed almost 360° without turning the camera tube. In addition, there is a 2x digital zoom with 1.3x and 1.5x (although here the quality of the image, usually decreases due to the low illumination in a dark room).

The handheld also has an LED built in to get a good picture of the insertion port even in a poorly lit area.

Conclusion:
I am totally thrilled with the device and it greatly exceeds my expectations. I was able to do all the work I wanted to do with it without any problems (I found all the cables I was looking for in the ceiling). At first, the price seems a bit high, but you get a top device that is super processed delivered. Just unpack it and start looking: no more installing apps, looking for adapters for the smartphone or sitting in a tight corner or niche with a clunky notebook, thanks to the self-sufficient display. The pictures taken in HD quality are super and the endoscope is super flexible to use thanks to the 2 cameras. There is a clear purchase recommendation for home use.

The k&F Concept name has been synonymous with quality and functionality in endoscope cameras for years.

This three-lens camera, model GW45.0001, is no exception.
Unlike the cheaper endoscope cameras from k&F Concept this camera is housed in a hard case and can be taken anywhere, permanently protected.

Thanks to the included 32GB micro SD card, I can start using the endoscope right away. The 2600mAh battery is also pre-charged and allows wireless operation. Should the battery ever run low, operation can be continued with a powerbank.
Thanks to the good user manual, I quickly familiarized myself with the functions. The device can be operated comfortably with German menu guidance.

The areas of application are diverse. The water protection allows penetration into areas that are filled with water. This makes it easy to explore clogged pipes, and the three lenses also provide three different scenarios (straight ahead, left, right) of a situation. The integrated light on the probe travels with the camera as it changes, providing noise-free resolution for sharp photos or video. The light can also be dimmed if needed. Date and time are integrated into the medium for both functions. It is possible to view or delete recordings on the control unit at any time.

The panel has a microphone that records sound during the video function. This makes it possible to take notes during the inspection.

The probe head measures just under 5.5mm. This allows the camera to get through pipes just fine, and it snakes through the engine compartment or through pipe runs in the wall just fine with a 5 meter cable length.

What I might be missing from this unit would be a magnetic mount and a 1/4 inch thread for a tripod so I can fix the panel when I'm running the 5 meter hose. Sometimes this requires 2 hands and then you are looking for a secure place to put the panel where you can then keep an eye on the screen. The screw-on folding stand is not always helpful. If a 1/4 inch tripod thread were used for the stand, you would have killed two birds with one stone.

The accessories are very useful with this model. A hook or a magnet can be attached to the probe. With these two helpers, there is the possibility of fishing small parts out of pipes. If I had this achievement three weeks ago, I would not have had to unscrew the sink siphon to get to a piece of jewelry. If the trinket had already ended up in the wall pipe, I never would have gotten it out without the hook. It may even be possible to clear blockages in the pipe with these attachments. k&F Concept has thought along wonderfully with these two accessory parts.

I was impressed with this camera. Affordable and worked as it should. Was definitely worth the purchase. The only thing to be aware of is the length of scope. About 16’ or so. If you have a pluming issue as, I did, and your issue is further than that…you get the picture. See what I did there?

For the price, the camera quality is rrally good. Images are clear

If you are a serious diy guy or girl and want to save yourself a LOT of time, buy this. Just get it. Used it to find coolant leaks on cars, fridges, route wires in walls, find parts that fell under the boat engines, pull out lost stuff from impossible places, you can take pictures of serial or part numbers without having to take stuff apart before ordering a replacement and so many other uses. The nerves this thing saves are irreplaceable. Love it. The picture quality is great, the case is very solid and the whole thing just works. Battery life could be a bit better, but never ran into issues if recharged after each use. Fantastic and solid product.

So let's start with the processing and design of this device, the quality here is really convincing the preisleistungngsverhältnis on a very suitable level! Supplied here you get a nice little case which shows the endoscope camera directly when you open it, it is cleanly processed and the buttons have a super pressure point! When turning on the camera goes directly on and you can start immediately Bsp in an inspection of a vehicle! The image quality is very usable and absolutely sufficient! The device even has a small light on the back which is quite good to use in the dark on the whole the device is handy and recommendable therefore there is a purchase recommendation from my side think here you can do nothing wrong, well suited for workshop!
