I'm always a bit leery of the triggers that are also motion triggers because sometimes that means the trigger is fired by the motion of the lightning happening -- rather than than the infrared pulse that precedes it, which is what the Lightning Bug and the Stepping Stone Lightning Trigger are activated by. I had a Opteka once that claimed to do all the things that the Pluto does -- but it missed every lightning bolt.
I know their site claims to use infrared too, but even Pluto says on their Instagram that "Some users have use the Lightning mode during daytime successfully." (emphasis mine) That's not good enough for me.
