SJ 4000 use

Delivered the items in a plastic package without additional accessories.

The first inspection was positive. Despite the low price the item and makes a good quality impression.

The adjustment can be changed easily and without much effort by the adjusting screws. That works very well in practice.

To secure the cam principle does not require any adapter. The cam can be screwed with the outdoor casing directly to the suction cup tripod. For only the screwed already when delivered sliding adapter of the holder must be unscrewed. However, when the cam to be slid on the sliding adapter included in the delivery, it still needs the matching counterpart for the Cam. When this adapter is SJ4000. As it looks at the Gopro I do not know.
Have uploaded to the customer photos, which adapter is required for this.

The suction cup can be easily attached to the disc or well on clean car paint. On sucker a click lever for easy attachment is attached. This allows the suction cup mount without much effort.

Also known as the dashcam Cam is usable.

I have now tested the mounting on the wheel and the car paint while driving. Both variants have convinced me. The cam had a good grip and has not additionally wobbled in the holder.
By means of various settings great shots can be so realized.

Conclusion

For the low price you get a good and usable suction cup tripod here.
