I bought this for my fiancee at the time who had several things to plug in, but did not have the space and would keep rotating plugs. This was able to help her organise the place better and charge multiple things at once. She absolutely loves it. It even has ports for phone chargers, which is very useful. The quality is very good as well. Strong and durable and looks good once you take care of it. Can blend in well and it looks good aesthetically.

Are you tired of moving furniture around to find a plug?

Size: 6.5 Ft, Color: Black

I hate moving my room around to find an open outlet, I needed something that had a surge protector because of my gaming computer and I also have a lot of stuff that needs plugged in. This has a lot of plugs, I love that they are spaced out and have the USC and USB at the top. The cord is pretty long so it reaches a good length. It tells you if its not protected by how it lights up when you turn it on. I highly recommend and I would buy this again if I needed another one.

Thin, durable, good plug orientation

Size: 6.5 Ft, Color: Black

This has been great for behind our entertainment center. We have a lot to plug in between floor lamps, tv displays, PlayStations, and pcs. No problems so far and much better than chaining extension cords. Would buy again
