the retainer portion 112 such as one or more of the plurality of walls 118 can be made of a material e g a polymer or a silicone that is sufficiently flexible to permit deformation e g compression bending or stretching of one or more walls 118 so that the channel 116 can be temporarily widened while sliding the lens component 110 onto a communication device but at least a portion of one or more of the walls 118 can be sufficiently stiff rigid or resilient to urge one or more of the plurality of walls 118 to return to its original position and thereby exert a gripping force against a portion of the communication device the material of the retainer portion 112 especially the region on the inner side of the walls 118 within the channel 116 can also be tacky or somewhat slide resistant to enhance the gripping of the retainer portion 112 to the communication device in some embodiments the gripping force and or slide resistance can reduce or eliminate the need to attach a permanent or temporary mounting component to the communication device for example the lens component 110 can be repeatedly attached to and removed from a communication device without requiring though not prohibiting installation on the communication device of a separate permanently or semi permanently attached mounting component such as a bracket magnet adhesive or other fastening component thereby providing ease of installation while preserving the original overall shape appearance functionality compatibility e g with other communication devices or cases and or feel of the communication device when the lens component is removed the retainer portion 112 can also comprise an upper wall 120 that.
