This USB 3.0 hub has been in use for about three weeks and has worked perfectly. I have a Lenovo M73 Tower and it has two USB 3.0 ports and four USB 2.0 ports. If you use BlueTooth, Wireless or Audio they seem to work fine and fast. Some people say that they experience interference when using some wireless devices connected to a hub. My WiFi connection is connected directly to the PC. I was very concerned when I checked the USB port with "USB Tree Viewer" and it showed that this hub is USB 2.1. Other software reviewers showed the same. I checked the USB devices in Windows 10 Device Manager and identified them as SS (Super Speed) Hub + Charging (3.0). Also checked with DXDIAG for Windows. I've noticed an improvement in the speed of my wireless internet and other USB 3.0 devices. Also connect USB 2.0 devices and they work fine. I used the customer support chat service and was asked to check some drivers and USB status. According to them it works correctly. As for the speed check to see download/upload speeds for drives - I didn't run it. Good hub for the price. If you have a desktop computer and multiple devices, I would recommend a 7-10 port USB 3.0 hub. You will probably use ports someday. If you have a laptop with multiple devices and a phone, this one is great - smaller and lighter, plus fast charging. He really does all these things.
