Has anyone tried these SnugPlugs?

@ozzy  it looks llike they go into the plug and thus are obviously non-conductive.  So now the plug is making contact only with the outside half of the receptacle.  Is that right?

Might be great for the loose plugs I seem to encounter on planes ....

carlsbad2,

Yes, I think that is right. But it may just be in the front and the rest of the AC blade is still the same. That is why I didn’t use them in my Audio System.

A high quality AC outlet grips much better , I bought the $200 Furutech  outlet very good and sonically better but take a full 200 hours to runin.

An electrician friend of mine said that they will ruin the outlet. Over time the contacts writhing the outlet will be pushed back and loose the ability to hold a plug with or without them. For 3-5.00 it’s best to replace the outlet. If it’s a heavy use outlet buy a better brand, e.g. Hubble
