The Cam is making good shots for the price. Of course, they can not compete with a GoPro Hero 3 BE, but you may not expect at this low price. For the hobbyist, the results are quite adequate.
The SJ1000 can also very well be used as dashcam in the car. License plates and other details can be seen very well on the photographs.
The supplied brackets are not particularly high. I mean, if the cam is mounted on the windshield, you get blurred images, because the holder can be left and right turn. With each bump then moves the Action Cam.
For a large action house the way you can also order replacement batteries. These then come directly from China. One can operate with an external USB battery Camera as well. The SJ1000 is charged through a Micro-USB connector. So you can use a cell phone charger with matching plug.
