Great!
Product is honestly amazing and would recommend this to others.

So many people like the ollo clip and other cheap lens systems.

And then people discover that Schneider, yes the world class opticals company from Germany who make lots of expensive glass including B+W camera filters, have made iPhone/smart phone lenses.... and you know this is the one to get.

I have only rave reviews to share about this lens kit. It is sharp and easy to use. Also a lot of fun in general.
The only not so fun thing is that the shell-case cover that snaps onto the iPhone is terribly difficult to pry off if you wish to do so.
It would be a bit better if it had a rubberized edges I think..but that said, maybe folks will never take the cover off once placed onto the iPhone.
Regardless it is the best play optics for the iPhone I have tried. I should mention that I make my living with film and photography. I use very high quality gear to insure image quality. I have owned several Century Lens products for my pro Film and Video gear. It has always been tack sharp and beautifully polished, coated lens glass. This is no exception! Samples on eTrips web site.

Easy to install and to use, great pictures. It lets you have fun and you get original pictures to share.

I've really been pleased with this product. Makes the expensive cameras much less needed. The wide angle and telephoto lens work very well. Easy to attach and very portable in the pocket.

My only recommend to the manufactor would be to make the case a little more sticky. One has to be careful as the case is slick. Otherwise a great product and I'm just careful handling the phone when in this case. Only use this case when I'm hiking or need the extra lenses.

Just hope they come out with a case for the iPhone 5 and allows these lens to be re-used.
