There are some of our customers who bought our product Car Cup Holder Phone Mount, they complain about that the bigger cup holder is not suitable for our product. Like the size large than the 3.4” cup holder, our cup holder maximum size is 3.4”.
We committed to providing more top grade product for our customers, so this problem makes our high attention. After more improvement, we decided free to add an accessory to solve this problem.
The Silicone Extend Case. Like the name, this accessory made for silicone material. It is mini and easy to install. More important is this little thing could add to 0.6” for Car Cup Holder Phone Mount width, perfectly solved problem like these bigger cup holder.
About the installation, firstly twist the cone-shaped part on the top of the base until the 3 pieces expand to the suitable length. At last, put the silicone case with right direction (TOPGO logo readable) then put it into that 3 pieces expand surface and twist to fit your cup holder.
