Bullseye archery makes this lens, has anyone used it, also does anyone else sell this type of lens? It sounds like a good idea?

I JUST SUCCESSFULLY SHOT A PERFECT 450 VEGAS ROUND WITH MINE LAST NITE. I REALLY LIKE THE WAY IT WORKS., SIMPLY BECAUSE I'VE BEEN TO SEVERAL COACHES THAT SAY NOT TO AIM. FLOAT AROUND THE SPOT YOU WANT TO HIT AND MAKE A GOOD FOLLOW THROUGH AND THE ARROW WILL HIT IT'S MARK. WITH THAT LENS IT MAKES IT MUCH MORE EASIER TO DO.
