Cons:
- I thought the rod was longer
- The noose of the phone is not super strong
- No manual (annoying when you do not know to grid)
- Not compatible with the S view Cover open (S4 shell with sensitive dial)
In summary:
It's a great value for money, it is compatible with other phones and accessories and more are significant.
I recommend it if you do not want to put miles and cents in a highly useful in the car accessory.
