I have their low-voltage 3-mode module in an L2R, and it makes a nice solid light that I really like.
I didn't really care for the sharp bezel it came with, so I bought a smooth bezel for about $5 I think from sbflashlights.
It does have noticeable (to me) PWM on low and medium. Not enough to bother me, but some people might find it distracting.
