This LifeProof LifeActiv QuickMount 78-50360 adapter features industrial-strength adhesive for attachment to most phone cases, allowing you to use your phone with other LifeActiv QuickMount accessories (not included).
This product does exactly what it says it will. It works well, and is fairly simple to use. Its main negative point is that you have to attach it permanently to your phone or your phone case, which limits your ability to change phone cases without purchasing more adapters. However, that is something I was aware of when I bought it, and so I accepted that fact. Overall, I'm pleased with the product.
