Quoted from Who-Dey:I just installed the IMDN loop adjuster kit and wow what a difference it made. My loop shot from the top right flipper was probably registering 60% of the time roughly and after i put it on tonight i hit the loop at least 25 times and it counted every single one of them. I cannot recommend this product enough for people who are having loops that don't register.

Quick question, do the two opto shields install on both sides of the same opto pair (ie transmitter and reciever), or one shield on one pair in the side loop opto, and one on the opto pair in the right loop too?
Their install picture shows just one shield installed, but I'm not sure if that was intended to be the completed install pic.
Does it matter which side of the opto pair you install on if it is one shield per pair?
Mine registers 90+% of loop shots, but it's annoying when you get robbed for a major jackpot or whatever.
I might also try just making my own shields too out of sheet metal or something, though I have yet to remove the opto pair and check if there are any major hurdles to doing that...
