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

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
