The device meets only the price according to the purpose: The resolution, respectively. the quality of the captured images thus adheres very limited. The front part of the camera also allows for only a limited deflection angle, which excludes or at least some applications can be very difficult (eg insertion into a tube of 4-5 cm in diameter and a 90 ° bend on the road). Practically, nevertheless, that you can hold pictures with it. However, not every image is stored correctly on the PC. So I had, for example, from 10 shots 3 frames which were 3/4 only green or blue. An immediate check of the stored images is advised accordingly. The saving is actually very difficult: Each time you record you have to change again the storage path and the aspect ratio (the latter only if you .jpg .bmp the prefers), and completely capture the filename instead of proposing the previous. 3 program variables and 6 Programmzeilchen could have avoided this. Very practical has otherwise proved the opportunity for me to bring a small (supplied) hook on the front rod end to an otherwise inaccessible, keyed particles to dissolve and fish out. Conclusion: For elementary purposes it is sometimes very happy to have the device, even if you have to plug compromises. You can always get hold only for his money.
