Review on Capture More Than Ever Before: Wide Angle And Super Macro Lens For Mobile Devices by Jamie Dawson

Great for capturing as much as possible. Works best for wide landscapes, but I've used it indoors. Sadly I lost mine during my trip in Japan. I used it with the Essential Phone. It can take some time adjusting it to avoid dark corners. Once you know the sweet spot its much faster. I've noticed some blurring on the edges most likely to do with mis-alignment. You'll probably need to crop out the edges if you don't match it perfectly. Useful if you don't want to carry a full size camera. Not very practical if you want to use interchangeably with your stock phone camera lens unless you put down some tape or marker for a perfect alignment to make it easier.
