From B.K. in Kansas City:
A great accessory for a great optic
I wanted an adapter to attach my iPhone 5s to my Swarovski spotting scope. I found the Swarovski adapter on the website of a major outdoor retailer, and went there to purchase one. The Swarovski adapter wasn't available, so they sold me an aftermarket/generic adapter that was awful (at best)!
Then, I searched online and came up with Eagle Optics. I ordered the Swarovski adapter from Eagle, received in just a few days, and I am over-the-top happy with this adapter.
Beautifully engineered, extremely simple to use and perfectly efficient. Two parts only...genius!!
