Small gadget for a very good price / quality ratio

I was a bit septic before having this small goal and finally he perfectly fulfilled its mission: to capture a wide angle for the beautiful scenery of Scotland or small rooms castles. Its small cover and allow its cache to protect well, especially if you travel a lot.
Another positive point: it does not damage the iPhone, in fact I was a little afraid that the scratches ... We just have to clip it.
Basically, it's a little gadget not essential, but that brings more to travel photos taken with an Iphone. It is on that you can not get it out each photo as it must then store it in his house, but to mark the occasion for a great photo yes!
Finally I find the price is right, making it an object at the right price / quality ratio.
