Familiarity: I've put it through the wringer
We picked up one of these lens to pair with my Google Pixel 2 phone for our backpacking trip to Machu Pichu. Very impressed with the quality of the glass in this lens and the Moment Case for that matter too. It was fun using the Fish Eye lens for photos for some creative flare. Just remember that when objects are close and located on the outer area of the shot they will be "bent" more compared to far away.
This was a perfect way to get high quality photos without take our big camera on our backpack trip when we wanted to keep our packs light.
