The whole course is plastic and the screw on the support seem still fragile. It will not compel under pain of unpleasant surprises. So we screwed each glass to get the desired effect. The wide-angle and macro are against solidarity. We must first screw the macro and screw on the wide angle macro without forcing if we want then unscrew everything easily. Note that the clip is a little loose and that we should not make sudden movement or risk seeing the clip shift and spoil the picture. With the case, the system takes better.
If the filter has not convinced me as the wide angle (too vague), the fish eye is well marked and allows him to have fun. The macro is used by cons really close and we must paste the goal against the object. In return the rendering is very good then as seen in the photo of a lemon tree flower (obviously depending on the quality of the optics of your smartphone, mine was pretty bad on Acatel mini Idol). In fish eye and zoom, it will go against by the editing box to remove partly vignetting.
Light weight (37.6 g) and takes up little space, this kit 5 in 1 lets have fun doing some original pictures. The wide-angle and filter are not quite convinced by me against. However, even when one has something fun for under $ 10.
