I have an upside down plug halfway up my wall that was really difficult to use and this is really been a game changer. It's flat against my wall so I'm not going to hit the cord and it it's long enough to put it in a more usable spot in the spare bedroom. The USB ports come in handy so I can keep the outlets free for my TV, lamps etc.

Nice oak corner shelf but check your measurements first

5 stars for the shelf, 3 stars for myself :-) This is a well-made oak corner shelf that looks great where I put it. The wood is nice quality and the construction is solid. Before you order though, do yourself a favor and check two things: 1) Make sure the size is actually big enough for what you need, and 2) Check that your corner is actually a true 90-degree angle. Turns out mine isn't perfectly square and now I'm trying to figure out how to position this thing properly. Good product overall, just wish I'd measured more carefully before ordering.

i’ve been wanting this shelf for quite some time and finally decided I’m doing it. I’m absolutely completely satisfied with the size the quality of the wood and the paint job. It’s made very well. I have to say I was surprised at how nicely sanded it was and ready to hang.
