PentagonLight Weapon mounts.

Just wondering how many of you have any experiance with PentagonLight weapon lights?

We sell them at the store I work at, but only the handheld versions. I was thinking of ordering their dual led/laser with ARMS mount for my RRA Entry Tactical carbine. Pictured here: http://www.pentagonlight.com/item_detail.cfm__id.382

I have the L3 Luxeon light,(http://www.pentagonlight.com/item_detail.cfm__id.246 ) and love it, but I havent had the chance to mount any of their weapon lights.

Let me know of any experiances with them, as they are a tremendous value compared to surefire and other "top shelf" brands.
