Has anyone tried these SnugPlugs?

They might make a tighter mechanical connection but I don't think they will do anything to make a tighter electrical connection.

I would replace the outlet before buying those. 

 Agree with replacing outlet instead.

clever problem solver for even light cords in loose outlets

alternate from Amazon: 15 for $6.

These are for the outlet where the cleaning lady always plugs in the vacuum cleaner and after 20 years, it falls out.  the right answer is replace the outlet. 

many use hospital grade outlets for audio.  one of the features of the hospital grade is very snug holding of the cord.  I guess you don't want the lifesaving equipment to come unplugged.

I have used them in places, other than my audio, video equipment, and they do keep the plug in tight.

@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

I would want to know how they change the sound before I decided on using them.
