These are pretty nifty. I was very glad to have the opportunity to try these. For optimal use, I removed my phone cover so that the lens would be closer to the actual iPhone lens. You get 3 lenses. 2 of these are screwed together. I remembered reading that fact in the product description. Unfortunately there was nothing in the packaging or on the box to instruct or inform. It is great that these lenses can be used on a variety of electronic devices. It comes with a small bag to carry everything in and the bag also serves as a lens cleaner. The outside edge of the box that these come in has a picture with a diagram to indicating what is included in the box. These screw in very easily. I had difficulty unscrewing the macro lens and the wide angle lens to separate them. Once I confirmed in the product description that they should come apart, I was successfully able to separate them without fear of making a mistake. The macro lens is great. I was not sure if it was working properly because it was out of focus. That's when I realized I had to move it in closer. The detail was amazing. It was great to be able to have photographic versatility with my phone. I very rarely bother taking a camera anywhere. Now I have three more reasons not to use my camera. Macro, wide angle, and fish eye. If this had come with some simple instructions I would have given this 5 stars. I would have been able to use it immediately and effectively out of the package. Without instructions, I needed to rely on returning to Amazon to read the product description.
