I picked this item up from the collect point today so this is my initial impressions.
In the package you receive two things the lens holder its self and a small bag to keep it in (a nice touch to have somewhere to keep the lens)
The build quality seems good for the price it dose not feel like its about to break at any moment.
i have tried the lenses very quickly the wide angle and fish eye are very impressive. The wide angle clearly has uses in a bigger field of view but be careful it dose distort and bend the image slightly. The fish eye is more of a novelty fun thing although it dose give interesting and fun results
i have not been able to test the macro lens at this time but a very quick test proved very difficult to get the iphone to focus
