This is the best option I've found for attaching a dash camera to my car

Multiple options of mounting is excellent

On top of that, this is also the most stable option

I took a chance with this because the image shows that it supports the Roav C1 as a mounting option

Overall, not bad if you're looking for the cheaper option

Mirror weighs near 2 pounds, believe this hardware can support that weight.–I’ll use the left configuration marked with arrows in my pic, might be able to use remaining adapters in other projects.–With needed configuration assembled, ball sockets seem to rotate smoothly–Wouldn’t hesitate to recommend to others, have more than enough pieces in this kit, so don’t expect to purchase another.–User instruction manual is very minimal so bring your own creativity to the project
