Do the magnets in the mounts affect my smartphone?

No. The magnets in our mounts will not affect your smartphone.


Can I use QI wireless charging with magnetic mount?

No. Once you attach the metal plate at the back of your smartphone or at the back of smartphone case, the metal plate will interfere signal between charging plate in your mobile device and the charging adapter. In order to use QI wireless feature, we highly recommend you attach the metal plate at the back of smartphone case and remove the case while you use QI wireless charging.


I use a case for my smartphone. Will your mounts still work?

Yes. Our mounts are designed to securely hold devices even with cases on them.  However, please be aware that thicker cases may cause compatibility issues.


Will your mounts fit my car’s cd-slot?

Although our mounts are compatible with most vehicles, we haven’t been able to test every combination. Please keep this in mind when shopping, so you can choose a mounting option that works for you.


Can I still use my CD player even with a Koomus mount installed?

Although the CD players in certain cars may be used even with a mount installed, we DO NOT recommend it.


What is the difference between the CD-Air and the CD-Eco?

Both are excellent options. Other than the aesthetic differences, the CD-Air can accommodate devices that are thicker and the CD-Eco can accommodate devices that are wider.



I was issued a refund, when will the funds come through?

Please allow some time for the refund to process. It can take a few days, but you should receive it shortly.
