Had the iPhone 4 version, which doesn't fit the 5. Not sure I want to stump up nearly £75 every time the iPhone form factor changes. I may try the £10 cheapo copy, see if that works OK (let's face it, these devices won't deliver Leica quality). Maybe I'll even be able to switch the Olloclip lenses onto the cheapo bracket.
In my view the Olloclip would be a more attractive proposition at around £25, hence my rating.
God only knows what the two one-star reviewers are doing, these work perfectly. I've cut the velcro strip into two halves, hung 15/16 cards from each, and hung them by the command strips as instructed, stuck to the wallpaper. No sign of them coming down. I've just ordered more for future years.
Only two downsides - P&P is a bit rich, and when I come to recycle the cards I'll have to pick off the velcro tabs, but not a big deal. The product itself has satisfied 100%.
