Only difference I can tell is that DX does not include warranty card and manual.... or it is not shown in the photos. Also DX does not show photo of the LED
the light looks a little on the heavy side. it has about the same weight as the stainless steel Fenix LD01 (both weight indications according to manufacturer's specs). what i already like about it is the threads.
the Rofis ER10 has the male threads on the body (like the Fenix) and not on the head (Klarus MiX6). thus great likeable constructions!!
I like it! The fit and finish are on par with the Fenix and Klarus lights I own.
The modes are well spaced,the switches feel firm and responsive, squared threads, nicely fitted o rings. The circuit boards have the Rofis name printed on them (I like that!)
Twisting the head at various angles works well and is solid, actually better than I expected. The sheath and lanyard are high quality . The sheath holds it both straight and angled.
I wish it would tail stand better, the end has cut outs on it for some reason , but It will tail stand on a flat surface.
I would buy a 2,3,4 AA light in the same style if they made one. I like angled lights .
Typically ships in 4 to 7 days* (7 to 10 during new year season) = NO STOCK at DX's premises, need to source from factory first. Most stuff can be gotten in 4-7 days and posted out then. Some could take weeks (then you raise a case to cancel, i have done that before).
In Stock: ships in 2 to 4 days (5 to 8 during new year season) = IN STOCK at DX's premises.
But still, we get a lot of serious complaints about DX. Just have to be mindful.
