The shot with the iPhone screen in all four possible settings (Wide Angle, Fisheye, Macro 10x / 15x) as sharp as without the caps this. Plugging works wonderfully, takes at the beginning but possibly a little longer, because you have to attach it to a specific position so that it fits perfectly over two lenses (the same covers! Rear & front lens). For me, the display sheet has solved the first plugging because the olloclip it sits neatly taut and virtually no game for iPhone case. With a little practice you manage even without the film deducted.
For me, a nice, high-quality accessory for iPhone photographers. The not just low price is reflected in a quibble product quality. My recommendation to buy!
