I ordered the lens hoping to get a mediocre result in order to shoot videos from a relative distance at a school performance. The lens arrived on time, however:
1) the base on which it is adjusted to attach to the camera of the mobile phone is poor, it does not hold its position even when you find the right spot with difficulty, making it impossible to shoot videos without constantly readjusting its position.
2) Its lens is relatively blurry and dark.
3) In my lens, there was a mark almost in the middle of the field of view, which could not be cleaned (probably it was on the inner side of the lens).
It was a completely useless item, I think it was the most wasted 16€ of mine (imagine if I had also paid the 45€ that some stores were asking for it). Back in its box and with my children's toys, who might find it interesting...
