I am lazy and impatient, but mine work great anyway. I acheive horizontal alightment automatically (just got lucky I guess) and vertical alightment is easily acheived by some light twisting. I do take care to remove the air bubbles from under the lenses by gently lifting the lens holders to force the air bubbles out, before I put the goggles on. Also I am sure I am sacrificing some vision quality due to the curved nature of the goggles themselves, but it doesn't really bother me, and seeing as how I can never get traditional goggles to fit right and I find them very uncomfortable I think I made the right sacrifices.
