Anyone have any experience/comment on these:

I use 'em on my Spike's Battle Trigger. I was having issues with light primer strikes on russian ammo. Not any more since switching to these. I recommend NOT bending the trigger spring.

it's a good product .. like just about everything else they make.

Thanks guys....did you notice any difference to trigger feel over standard springs? Not that I'm overly concerned with that - I'm primarily motivated to buy this for the long lifespan. Have a CS buffer spring that must've been in 10k rounds now, so using the same material for trigger springs makes sense to me.
