Replying to Smith Sensor Lense?

So who has tried this lense out? I've heard it's rediculus in flatlight but I was wondering what people on here think of it. Is it really that much better than a rose lense like the Scott Amplifier or the Gold lense Anon uses? I ski in the NW where it's foggy about 80% of the time and I want the best lense I can get for flatlight and snowy conditions. Unfortunately none of the shops in my town have that lense so I can't try it for myself.
