So far it works good to help me charge multiple devices.

Easy to plug in and does what it says. Works great, just what I needed.

I specifically chose this particular USB 3 hub due to the 3 cable it has. Other hubs have very short cables, which makes them difficult to use with desktop PCs. This longer cable allows me to plug it in to be desktop PC and position the hub in a convenient spot on my desk. It just works and gets the job done perfectly. All ports negotiate at USB 3 speeds.

Vacation rentals rarely have USB chargers in-house, so I brought this to charge up our devices. One of the slots didnt work but the others were fine. It kept us charged up for the week.

Pros: has 4 ports. Works immediately, USB 3.0 and USB 2.0 all works fine Cons: the housing has corners not rounded. It wont hurt but perhaps better if rounded smoothly.. For the value I think it is quite useful. Immediately I have added 3 more ports (as It still takes up one of my existing port). It works well without any installation. Just plug and play. I like it and would recommend.

A USB port expander has become a pretty common accessory to keep in your laptop bag, especially with the slow disappearance of ports, so for $8 theres really no argument. The Sanzang unit is small, very lightweight, and works perfectly. I just think it could possibly have been made maybe 25% smaller if all the space on one end hadnt been devoted to a blue LED. But admittedly I may be splitting hairs....

This is a plug and play device, very lightweight, and smaller than expected which is good - takes up less space. I really like it because its small and functions as advertised. I got this because I dont have many USB ports on my work computer to be able to hook up various external devices. This allows me to do so. Highly recommended.

I bought this usb port expander because my laptop only had one port and I needed 3 so that I could plug in my mouse, keyboard, and Sd card reader. It has worked great for that, there isn’t problems with devices not connecting well or anything. It is a great simple expander that I recommend if you need some extra ports.

works exactly like I expected

This is a great USB port expander. I ran out of spaces in mine. It works Great!
