iPhone 5S - Olloclip?!

[TorqueR]

Good evening,

I am a keen photographer who is interested in a clip-on lenses for the iPhone. Upon browsing eBay, a certain type of lense caught my attention - it's called the "Olloclip 3-1 Camera" and I was hoping that some of you may have it, have trialed it or used it. If you have any experience with it, would you rate or slate it?!

Thank you.

Thank you for your replies. It has given me a few points to think about. I have seen them for £35.00 on various websites and it was mainly this video which made me consider them;

Is that a good representation of the quality that I would find?!
