Totally worth the cost. Extremely happy with the quality & design of this mount. Vastly superior vs original mount included with C3X. Installed it in cold weather and still immediately holds up to removing and installing the C3X with every drive. No connection issues and extremely sturdy/stable mount wise.
Extremely satisfied with the product.

so far, no issues. easy install, easy to take comma off and on. quality product

I accidentally broke my comma 3X screen once because I was manually removing it every time I parked my vehicle, and now I don't have to worry about doing that after installing this.

Love it.

Comes with everything you would need. The custom USB C cable is quite nice, and the 8 degree shim included was very welcome. Everything works and is well made. I have tried the Mr One and there is really no comparison.

Product works great. Amazing customer service.

I was skeptical at first, but this is truly worth my money. There is a YouTube video from some guy named Erich. The mount is solid and very easy to attach/detach with the magnets. Thank you again.

I just installed a new mount for my Comma 3x in my Bolt EV. It is called the “Cross Glide Mag Mount for Openpilot Comma 3&3X”. It is different from the other QD mounting systems in that it uses a magnetic quick-release system that is horizontal instead of vertical. It is available from jankay workshop. In the early production unit I received the piece that mounts on the Comma required some fitting; I spent five minutes with a file and sandpaper and got it fitted without any real drama. Jankay is aware of this and I’m sure the situation will be remedied in future batches, but it really isn’t a big deal. I’ve included some photos. I was able to easily reuse the original Comma 3x USB cable.
