Shaky and not stable

My window suction adapter broke for my Old Shark dashcam so I got this one as their customer rep suggested. Installation was not very pleasant if you have an electronic rear view mirror with wire attached to it. The problem with this mount holder was the fact that instead of just having 1 ball-joint like the suction cup adapter, this has 2 ball-joint sections, from the rear view mirror adapter to the "rotating piece" and then the adapter for the dashcam itself. It might not seem like much of a change, however, once you started driving you'd realized that every slight rumbling from the road no matter how little it seems, the dashcam would shake. On the highway, if you go over any tiny imperfection, gaps, or anything that's not smooth out completely, the dashcam would shake, badly. Now, this did not happen on my previous window suction cup adapter and I'm not just saying it base on visual from the car but I had taken the time to view the video clips of the drive to see how stable they were. I did check to see if everything has been tighten up properly before I come to this conclusion. It's simply not a good design compared to the 1 ball-joint only. I would return this and just get one similar to what I had before.
