pellwrote a review of Edelrid HMS Strike Slider FG Locking Carabiner on June 16, 2016
Familiarity: I've put it through the wringer
I have been using three HMS Strike Slider FG krabs for a year or so. For indoors use this is the perfect belay carabiner. Especially when using it with Edelrid Jul 2 or Trango Cinch. This is the way I'm using this binner now days.
Yep, I mean this binner. Two sliders were destroyed outdoors. Locking mechanism somehow broke. I suspect it was dust or rock particles got inside and blocked it.
With this sort of issue I would not recommend it to any climber. Instead go for old screw lock HMS Strike FG.
