the finish is solid plastic, the threads are standard (I use it with a gopro 4 black but I think you can adapt other cameras / Action cameras), both items can be perfectly combined to cope with all sorts of situations, setting the locking arm is simple: Both kneecaps tightens and loosens through a screw hand centered on the arm, the attachment of the suction cup holds well on my desk (I did 've not used on a vehicle).
2 small tips:
- The base of the clamping screw GoPro is not provided, so you should use the one from your GoPro,
- If you attach the suction cup on a vertical surface, if possible wait 1 to 2 minutes before connecting your device, the air being expelled apparently gradually from the suction cup.
