5x XM-L flashlight or 79$

Hi guys!

I have found this flashlight at DX.... I think the price is good (79$) because in other site I have seen another brand for more than 100$ (if I remember well)

I dont know how it performs, I dont know nothing about the internals (driver, heatsinking, etc...) But...

Any has more info? I think there is a skyray with similar desing...

EDIT: yes, it was in manafont, for about 30$ more
