BluTecQ 3in1 Univ Magnetic Camera Lens

Do not buy this if you own an iPhone 6/6 plus, etc. Even though there is a picture of an iPhone on the back of the package, they will not magnetize to the iPhone. They magnetize to the fridge, but not for their intended purpose.

I believe it comes with a metal ring you can affix to your phone/case so the lens can stick to it.
