I also have this light, without the hex head thought. As selfbuilt sayd, the throw is very good, almost a laserlike beam.
Well, actually i even found it to be a bit too tight for my tastes, i've also got the U2-Style cree, personally i like its bigger althought weaker hotspot better.
One question, selfbuilt - did you get to compare it 1:1 with the D-mini, i.e. do you happen to own one?
Oh and on a side note... i had a defect with mine. Been testing the Ultrafire 18650's, and after 10 minutes of it being on in high mode, i cooked the led.
Weird, hasn't happend to me with the U2-Style, and although it pushes even more maH to the led than the SSC it does not get as warm.
Anyway, DX sayd they'll take it back (and pay my shipping costs), its good to know they stand up for theyr costumers.
They also sayd they will try to check those from now on before shipping.
Personally i believe the led wouldn't have been cooked if i would have taken the head-hex version instead of the regular one. Apparently the hex-head serves as a heatsink.
Hope this info has been helpful to you.
