My only concern is the Wide Angle which once magnetized made some bug my focus (the image blurs and I hear the sensor by lollipop) I just need to remove the lens to get everything in order, but hey it's a bit annoying (and oddly it does not do so with other objectives). Once the Wide unscrewed, the macro does not pose such problems. this is the goal that I use most.
If however you want to make blurred city lights like effects with the focus on the water droplets on the glass, I recommend the black targets because money quick to reflect on the glass in focus.
Finally and for the price I think this product is really doing well.
I use it myself to create my little personal image banks (textures, graphics creation) but you can just as easily fall for this to change the viewing angle of your camera or other security. It is also the force of a universal product like this: its use is not exclusively reserved for the back of your smartphone.
PS: I enclose a small macro photos I made upon receipt of the parcel, which arrived quickly enough to it (3/4 days).
