These are my quick first impressions of the Olloclip. I have this for my iPhone 5 and its small lens you clip over your phone to enhance your photos by allowing you have to have extra lenses.
You get a fisheye, macro and Wide angle lens with this option. It clips onto your phone very easy, the only problem I had with my 5 is that with the screen cover I had it would lift the corner of it, which then would create bubbles , etc.
The photos you can get with the macro lens are quite amazing, as you can see below.
As you can see you can get some amazing shots, using this lens I know that Cirque Du Soleil use this to inspect their guide wires, as you can get incredibly close up shots.
It comes with a small carry case so you can easily carry them around, it doesn't take up a lot of room and it easily clips on, as mentioned the only flaw I have found is it lifted my screen cover.
I am always interested in your thoughts so if you have any comments or feedback then please feel free to add any comments, or you can mail me here.
