The Teslong endoscope is delivered in a practical hard case. The scope of delivery includes the device itself, a USB cable for charging and data transfer, a 32GB SD memory card, two additional tips that can be attached to the probe, one with a hook and one with a magnet, a small Allen key, the you need to remove the probe hose, a suitable spare screw, a folding stand and operating instructions in different languages. In terms of quality, the device makes a very good impression, both the case and the keys feel very high quality. The operation of the endoscope is relatively simple and after a short reading of the, unfortunately somewhat poor, operating instructions, the device can be used. The picture quality of the is not outstanding, but more than sufficient for the actual use of the device. The 5 meter long probe hose is a bit stiff, but has the advantage that it can be maneuvered and pushed through narrow pipes better. What is also quite positive is that you can dim the LEDs on the lens, so you can counteract overexposure on reflective surfaces such as stainless steel pipes. In my opinion, the supplied folding support is useless, as soon as you use the rather stiff probe cable, the support no longer offers any support and the endoscope flies around. A magnetic holder or the possibility of attaching the device to a tripod would be desirable here, as this would make the work much easier. Unfortunately, the supplied manual leaves a lot to be desired. Only the essential operation of the device is explained, but how to attach the additional tips, for example, you have to find out yourself, this is absolutely not discussed. It also explains how to remove or attach the camera probe, if you follow the instructions exactly, the device is then ready for scrap. The attachment of the probe is like a USB-C connector, which is additionally fixed with a screw, if you insert it as instructed in the instructions and then turn it clockwise until it clicks, you will break the connector, so be careful. There was probably something sloppy in the translation, because on the English pages it is described in much more detail. The built-in microphone is a nice feature for leaving any comments while working, but unfortunately it also records all the button operations, which then become noticeable as a very loud click on the video. Overall, I would describe the Teslong endoscope as quite useful, both for the do-it-yourselfer and for semi-professional use. A little more effort in translating the manual and possibly a possibility to attach the device to a tripod would be desirable. In my opinion, the price is justified.
