Be aware that Southord has 2 sets of jigglers: The Auto Jigglers and Pin Tumbler Jigglers.
Auto Jigglers are for wafer locks (as auto locks are usually wafers) and Pin Tumbler Jigglers are for, you got that right, Pin Tumblers
I only have experience with the Auto Jigglers and they do wonders on cheap wafers. The Pin Tumbler Jigglers are (as I heard, never used them) very good, but take a fair amount of practice untill you get proeficient with them. I don't remember if it was BosnianBill or Kokomolock that managed to consistently open locks with spools with those. But other members that got them couldn't open anything for a fair bit of time.
Bottom line is, they are good. But you need skill to use them, so they're not a "magic trick" to open locks.
Go ahead, keep plugging away, picking on me! You will end up on bypass or with rigor mortise.
