Structure of the Selfie Stick
With the help of a Selfie Stick you can easily take self-portraits or group portraits with your smartphone.

Since UNC 1/4″ is used for tripod threads for cameras, among other things, the manufacturers orientate themselves on this. Unfortunately most Selfie Sticks you can buy on holiday are not always of good quality. Especially the processed thread is very vulnerable and can break quickly.
In order for the Selfie Stick to survive many holidays and trips, it is recommended to do some research in advance. Inexpensive models can be purchased from about 10 Euros.
