It is 2 in 1! Macro and wide angle (it unscrews in part 2) I thought it was a gimmick, but macro shots that I realized were bluffing! The wide angle is already more classic, but fine. 1 star less because on my phone galaxy s2 the wide angle magnet tends to distort the development of the device, I managed to have 70 net décallant in the lens to the center C ... is not ideal for that damage.
