Tiakia bike phone mount
If anyone is looking for a good and very high quality bike mount for his FP4, here is my recommendation:
Very high quality, stable and accurate fit for the quite thick FP4.
Nothing wobbles, despite the fact that the FP is quite heavy.
Completely made of aluminum and stainless steel screws.
And even for small money.
Top recommendation. I am super satisfied.
