Amazon saves the day!!!!! Again.....
Size: 4 Pack, Color: A-Ivory White
These adapters are AMAZING!!! I live in an old home and all the wall plugs are two prong. But it seems these days everything is three prong. I had no idea until I saw these on Amazon, three prong adapters even existed!!! Amazon, once again, you've saved me lots of frustration and made my life so much easier. Thank you!!!! Very sturdy. Well made. Excellent price for 4!!!!!

saved me in a house full of old outlets
Size: 4 Pack, Color: A-Ivory White
My landlord's house is really old and basically every single outlet is two prong which was an absolute nightmare for all my stuff. These little adapters just plug right in and suddenly everything works no problem, and getting 4 of them for under 10 bucks is a genuinely great deal. They feel sturdy enough that I don't worry about them coming loose and they don't stick out too far from the wall either.
