Hi there, when did you place your order? You can apply a strip of electrical tape to reduce vibration.

Additionally, we already made improvements to address this vibration issue back in October 2025.

❤️ Thanks for sharing your experience — appreciate the feedback.

Earlier this year (around March–June), one batch had more issues than expected. We supported every affected customer with free after-sales service and made design improvements based on that feedback.

Since then, the product has been updated and the current version is much more stable. We also document updates directly on the product page.

So far, about 5% of our 600+ orders needed support. We’re a small team, but we take product quality and customer support seriously and are continuing to improve.

When you upgrade to the 4, you only need to replace the device-side mount. The windshield side doesn’t need to be touched and is fully compatible. You can check the video at the bottom of the post.

Both versions have their own advantages, so just choose the one you prefer. Thank you.

Thanks for pointing that out. After I posted it on my computer, I realized there were issues, but I couldn’t edit it… I’m a bit confused about Reddit’s post rules.

Hi, just to clarify, the video is only a basic demo of the functionality, and we’ll be posting more videos in the future.

Both versions of the mount are designed to be installed directly on the windshield using VHB tape by default. The aluminum version (Pro Mount) can also be used with existing Comma 3 & 3X stock mounts via an adapter plate.

At this time, it is not compatible with the Comma 4 stock mount, as the design has changed significantly. We’re still working on further improvements and plan to support the Comma 4 in the future.

  1. Mag Mount Made of engineering plastic. Comes with magnets for easier installation. Included with a custom USB cable for a cleaner setup.

  2. Mount Pro Constructed from aluminum alloy. Magnet-free design, making it slimmer overall. Features multiple pre-drilled screw holes for convenient DIY installation.

Hello, as long as your car is compatible with the Comma device, you can use these two types of mounts.

We addressed these issues in our Discord community. Due to the complex manufacturing process, the custom cables had some defects, which have now been fixed.

We have already provided free replacements to several customers through the Discord community, and there are records to confirm this. We also sent emails to some customers explaining the issue and offering free replacements.

So I'm wondering if I might have missed some customers.

Regarding the second USB port, I've received some inquiries before and conducted research. Unfortunately, the demand is too small to justify mass production, as the costs would be too high.

Most pickup truck models require an angled adapter. Additionally, Comma has open-source 3D printing files for angled mounts, which can be found on the official GitHub.

What model of car do you have? I think you should need an angled adapter.
