Beartech Side Slidemount For C4, Openpilot Slide Quick Mount SET for Comma Device

Does the job

First off, I have to give Beartech credit for their customer service. They were incredibly quick to respond and kept me updated the entire time. The C4 slide mount does look and feel a little rough around the edges. I believe most of the components are 3D printed, so the texture and finish are not going to feel quite as polished as a mass produced product. That said, it works great. Your Comma 4 will look a little Frankensteinish with it installed, but the convenience is absolutely worth it compared to constantly plugging and unplugging the device. The sliding mechanism could definitely be smoother, but it works reliably and does what I need it to do. I would probably skip the case, though. The zipper on mine broke almost immediately, and I think you could find a better case elsewhere.

Need Nonmagnetic Version

I liked the ease to remove Comma 4 from the windshield but magnets interfered with the fan. I am looking forward to the update to the nonmagnetic version of this mount.
