These are fantastic!! And so simple to use.The plugs for my cable and internet are big and heavy. And the outlets are loose. To the point I had tried taping the plugs into the outlet to hold them in place.I really wondered if these would do any good.Yes they do!!! Put them and the plugs into the outlets and they stayed put!! No falling out.My biggest problem is that they’re clear and small and with my eyesight, difficult to see when I dropped one. Maybe I should have gotten the glow in the dark. ?After I dropped the one, I put it between the prongs of the plug and just plugged it all into the outlet. Easy peasy.I have other loose outlets, so now I’ll start putting these around the house.Would definitely buy again if I run out.
