Kacoco Anti-Gravity Case Magical Nano Sticky for iPhone 5/5S/SE with Can Stick to Glass, Mirrors, Whiteboards, Metal, Kitchen Cabinets or Tile, Car GPS, and Most Smooth, Flat Surfaces

Both surfaces have to be clean without any possibility for even small amounts of debris in order for product to stick.

Once you put it in your pocket it will never stick again I was very disappointed when I received it

It's a good case but the sticky part does not stick as well as I hoped it would

Thanks

Exellent

Very good!
