There were held the four specified lenses, only three lenses in the delivery. However, the function is ok. The glued-ring holds (for now). Look also ok. The stated 180 °, the lens but not (Samsung S3 mini). A maximum of 120 °.
Addendum 01.26.2015: On the first Rezesion towards me had written to the seller. (First-class customer service!) There are still 4 lenses. You can unscrew one of the 3 lens apart, and then the 4 of the article description.
