Look I'm not a fan of any sort of lightning trigger to be honest and basically don't use them. Even the best of them tend to miss much of the detail in a bolt during the initiation stage before the trigger can react. Fact is once light starts to fade there is absolutely no need to use a trigger anyway and even in broad daylight there are techniques that will better capture detail in lightning like ND filters etc.

So yeah I can't really comment on that particular device sorry.
