Has anyone tried these SnugPlugs?

Furutech GTX-D Rhodium outlet or Cardas 4181US Duplex Power Outlet are way to go. Lot's of these fora too.

I replaced my AC outlets with medical grade outlets and they hold great. I would like to find something to snug up my IEC connections. I have 2-3 that are jiggley and I’d definitely like to tighten them up.

Sounds like another 1/2 way gimmick, God knows audio has enough of them. Take the hospital grade advice.. will still give you full contact, +solving the jiggle problem. Don’t worry about any of the burn in BS or high dollar supposedly audio specific outlets, do worry about diminishing returns.
