GREAT for older homes and demands of modern technology!
Color: White
This item is working out well for me. I am visiting my son and daughter-in-laws home that the electric outlets are not updated. So the two prong plus the outlets on the power work out very well. GREAT purchase!

This is exactly what was needed!!
Color: White
This is a nice unit. I got it as I have started traveling a bit. It is a headache to try to figure out where to plug everything in to get charges. Especially when you are staying at people's houses, I don't like bothering them. I can put this in my laptop bag and bring it along with all the cords that are still plugged in. I really like that it is two-prong plug and the cord swivels. It will work in any plug-in and location. It costs a bit more than some of the others, but I think it is worth the extra few dollars.

Great
Color: White
Great product. Fits perfectly in my house. Only reason I gave 4⭐️ is because the plug has been loosening out of the outlet and making my tv turn off. The only reason I believe it’s doing that is because of the plug and how it can turn flat. Never had the problem with my tv before using this.
