The product is very convenient. I bought 2 different cars. Renault Megane 3 last generation, it fits perfectly. A BMW X1 last generation (not my car so I did not do the proper tests), the notches of the latter were further apart, as it is hard plastic is difficult to want closer without fear of breaking. Despite all the media like enough. Stay tuned. Otherwise the position of the smartphone is very convenient, I possess a broad LG G3 and returns smoothly.
I hope only that the spring system will take time.
