The lamp makes wi all Fenix lights a solid impression. Like other buyers have already remarked, is the weakness that immediately catches the eye, flush the conclusion from the glass to the housing. Here would be an edge, as defined by the other Fenix models that I know have all been installed to protect. When it comes to brightness, it is in some of the same with the Olight i3 EOS or Kraftmax X100. The optical sound is rather the yellow whereby the lumen ahead of the other loses subjective. Since I use fewer rings but rather loops for attaching to the rear end, I have no problems with the switch button. Unfortunately, here is no loop in contrary to the other Fenix models. Replacement seals are included. Priced the lamp is above the others mentioned earlier. Due to the lack of edge and strap not supplied only three stars.
