Works perfectly for what I needed
Size: 5 FT (2 prong plug), Color: White
We have an older house and I needed a 3 prong plug in our living room and this has absolutely done the job. I love that I can now plug my computer in and as a bonus, I can charge my phone if needed. The cord link is longer than I needed for the living room but worked great for a recent trip.

Great for behind a dresser
Size: 5 FT (2 prong plug), Color: White
Works great. Plug lays flat against the wall. Doesn't charge great on USB C ports, but it'll get you by. USB charging is 2 out of 5. Quality seems 4 out of 5.
