I was using a competitor's version that required a case for the phone and additional pieces for each optic. I hated that I had to keep switching out my phone case in order to use magnetic charging, so I decided to give this one a shot. It's exactly what I was looking for. I love this adapter. It's very quick and easy to attach to the phone, and lining it up properly isn't an issue at all. The connection to the scope's eyepiece is also vastly superior to what I using. This thing works smoothly and rapidly locks down to keep everything stable. It's great that I can use it with any optic without swapping any parts. The only minor downside is that it's a bit heavier and bulkier than the other adapter I was using, but it's not bulky enough to really matter much. I can still easy fit my phone in my cargo pocket with this attached and have it at the ready in a couple seconds. It was worth every penny.
