Review on 📷 iSportgo S30 Dash Cam Suction Mount with 10 Joints for Popular Dash Cameras and GPS Devices: REXING, Z-Edge, Old Shark, YI, KDLINKS, Falcon Zero, Transcend, Crosstour, VANTRUE, GoPro Hero, and More by John Murphy

I needed a replacement suction cup for my Byakov DVR. This mount comes with a variety of attachments, but unfortunately only one was close enough to the original to use. However, I had to file a small plastic tab to fit the mounting groove on the DVR. It took a while because I had to file a little, check for fit, file a little, check for fit. If I filed too hard, the mount would be too loose. Apart from that it works fine. I'm sure there are several DVRs that perfectly match the attachments that come with this mount, but Byakov wasn't one of them.
