Received this morning, two days after order! The use is very easy, is screwed onto the clamp the goal that we want. I recommend removing the protective shell of the phone for optimal results. The fisheye is really great in the front because we recover the great effect angle / rounding with a round-shaped image is less successful on the back goal. The wide angle lens (screwed to the macro) is really good too. By cons I find completely unnecessary macro because it really takes to be glued to what you want photographed. If you are not very convinced, made a comparative picture with each goal, the difference is obvious! Only small thing: the development is rarely mounted with extra objectives, so it is often given a lil finger swipe to redo (there is more handicapping!). For the price is very correct! (FYI I have a galaxy s4)
Sorry the room was a bit dark for photos! 1 = Normal Front camera Fisheye 2 = 3 = Fisheye 4 = Wide Angle
