Lots of nice features
Size: 5 FT (2 prong plug), Color: White
664Very nice. Even the slots on the sides will enable a larger than expected plug. Wish they included the screws for mounting. Didn't think it would be a big deal as I always keep the extras from projects, but it would have been a nice touch. If you do mount the power strip, it does reduce the size of the plug it will accommodate on the sides. Also wish I would have purchased the longer cord- NOT the fault of the product. Love the flat angled plug! I'm using it behind an adjustable bed frame that moves several times a night, so knowing I won't accidentally knock it out of the wall is nice. And you can easily use both wall plugs. Also very convenient to connect the USB & USB-c plugs without the bricks.

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.

GOOD VALUE/GOOD PRODUCT
Size: 5 FT (2 prong plug), Color: White
FINE. HOWEVER YOU BETTER UNDERSTAND HOW MANY WATTS EACH DEVICE IS PULLING IF YOU TRY TO USE ALL 12 AC OUTLETS. GOOD VALUE

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.
