This small device is fun and I love using it. The picture quality is amazing, especially at wide angle, but also to the TV. Here are the benefits: Not too large, quite handy. It is always nice to hang it from a smartphone. Can take photos while being disconnected from the smartphone. The quality of images. It Makes pictures rather bitten and did not need to flash indoors. Digital noise pretty well contained when there is light indoors. The disadvantages (with iPhone 4): The device sometimes has trouble connecting to the iPhone 4, which is maddening. The unit starts fast but the photo a long time to register: several seconds. Really not suitable for snapshots. Referred not always fluid, that is the least we can say with an iPhone 4. When it's really dark, digital noise increases sharply. CONCLUSION: This is a fun device that makes better pictures than most smartphones, but it can not claim to replace a real camera, at least not with an iPhone 4 too slow.
