The hiLO's sticky pad attachment is slow, cumbersome, and finicky to put on. It's also frustrating to use if frequently going back and forth between portrait and landscape mode as i do. A magnetic attachment w the magnet on the lens is fast to put on and align to the phones camera and easily adjustable between portrait and landscape modes. Having now used both, i much prefer the fast ease and adjustability of the magnetic attachment, even though, the small lens of the hiLO is magnificent by comparison. I went back to the small magnetic lens because is it so much faster and easier to use. I want hiLO to succeed so am offering the above suggestion.
