Cutter MR11 narrow quad optic

Hi all,
I'm about to order a quad Cree R2 MR11 kit from cutter with the narrow optic.

What im asking is has anyone had any experiance with this optic, I have heard of some other optics people have used however this one will fit my housing extremely well and is the degree i want (4deg)

If anyone has used this optic please give me any info you can, Pro's Con's, Beam shots etc

Thanks in Advance,
Bradley

I bought a couple of these a while back. I was not impressed. The diffuser softens the hot spot more than I could use, and the beam angle was more than 4 degrees.

They do fit the MR11 housings without modification, The fit in my housings were a bit loose but manageable. The pocket for the Cree dome fits well but does not snap over the ring. It rides on it.

I think if they had left the center of each focal point clear and diffused the remainder they would have had a winner.

Just remember that is only my limited opinion.
