It allows three additional additional USB ports to connect peripherals to the computer. It is small and required no special connections. It has four slots but takes one so that is why the net gain is three. I would have preferred a longer cord so that I could attach it to the top of the laptop rather than letting it hang off the side where it can bang around if not on a table.

Had to start working from home and I needed a USB hub and found this one and it works great, I have a scanner, keyboard, connected to it because all of my hubs were connected to my monitor and other items I was using, but this little hub have done its job without glitches

Exactly what I was looking for and the price was even better. Not bulky not in the way and does what I want it to. The price caught my eye and I had a 5 dollar reward so it made my purchase even easier. Oh the usb fits perfectly and it does wobble when I move my laptop.

I needed a few extra USB 2.0 spots on my computer for a few desk peripherals and this little hub works perfectly. I have it plugged into the back of my computer where it's out of the way and have had no issues with it. Worked upon first use!

This works as I expected. I needed extra USB ports because my mouse and keyboard take up 2 ports leaving me with only 1 port. The cord is really short. Even a slight 1/2 inch longer would be much better.
