If there is no suitable phone case available for the COMPIT smartphone holder, a universal adapter is available that can be attached to an existing hard case. Silicone cases, soft cases and multi-part flip cases are not suitable.
The self-adhesive mount should be positioned as centrally as possible on the case. The adhesive film ensures a very strong hold. The smartphone can then be attached to the system by placing it onto the oversized bayonet mount and twisting it into place.
