Bests & Worsts Reviews from Amazon

Read all the way though if you are thinking of buying this device and care that your computers continue working! My first impression of this product was very good. It is built very well, and the included cables are excellent. My input line is connecting to a 4-way USB hub made by the same company (connected to mouse, keyboard, webcam), and my two outputs are a Surface book 2 and a self-built PC with hardware about 2-3 years old. The hub works OK with my Surface Book. The usb devices connect easily and quickly. If left on for a while, my keyboard will occasionally disconnect, but otherwise things were ok. 3.5 stars on this front. Where things got bad was with the connection to my PC. Especially around startup, some or none of my devices would consistently connect. I am an experienced PC builder, so I tried to investigate the issue. It seems that this device has a severe issue that interferes with the PC's BIOS, which messes up driver connection with the USB devices, and even hinders startup. That's right, this USB devices sometimes hinders my PC from startup and one time even fooled my BIOS into changing my boot order. Often I will power the pc on, and the fans will run only for a second, then shut off. Then, if I disconnect this device, the pc turns on and runs perfectly. Or, at other times, with the device connected the computer will power up fine, but then I will get a "fatal OS error". On top of that, even at the times where the pc boots fine, windows consistently gives me errors of "Your USB device is not working properly", and the lights on my keyboard and mouse often flicker as the devices try and fail to connect. I have never had this issue on any other usb device with this PC. Looking at the comments from the USB 2.0 version of this device, some people are reporting that the device pushes a back voltage to computers, which violates the USB specification and is very dangerous to computers. This would be a truly unacceptable error, as it could easily be the cause of my troubles, and could certainly destroy a computer. Overall, I have come to have no trust in this device, even as an experienced engineer and PC builder. BEWARE and do not buy. I will be returning my device and asking for a refund.
