Plugs in and works great! I had all 4 ports in use at once copying data without any issues. Does what it does well. Enough said.

This is the best little computer accessory I have bought. My new laptop has its USB ports on the left and right at the front of the keyboard and I am always hitting anything that's in them. The plug of the hub is smaller than most flash drives and the plug for my wireless mouse so it doesn't get in my way. Terrific product. I love it!

This inexpensive, sleek little product works well with my MacBook. I have my iPod cable, printer, and mouse running through it but when I plug in my external hard drive the computer doesn't recognize it. But it still serves my need as I can use the second USB port on my Mac for the hard drive and the Hub for everything else.

I was looking for a simple hub for my laptop. As it's not my primary computer I did not want to spend a lot of money. I was surprised to find this hub on Amazon for under $10. This is a great product for the price. Works great. I've had no issues and everything I've plugged in has worked well. Also bought my daughter one for her laptop. She is at college. She keeps all her USB accessories plugged into the hub, which allows her to just unplug the hub from the laptop (rather than removing 4 or more separate USB's) to pack up her computer for portability. Extremely pleased with this item.

Data transfer speed is excellent when all device are connected. No issues with the hub. I like the square design , buy they should improve the design so that we can either twist the USB inside or clip it to side when we travel...
