Review on High-Performance USB 3.0 Hub - 10-Port Powered USB Hub 3.0 with AC Adapter - Multi-Safety Protection USB Splitter - Aluminum Charging Hub with Cooling Fan and Mounting Brackets - Ideal for Multiple Device Charging by Shah Moser

Difficult to keep 4 or more USB devices connected for charging and data transfer. I don't know what it is, but at some point the devices give you data but stop loading, or it seems like there is data but there seems to be fragmentary transmission results. This hub seems to conquer everything. I can keep many devices connected, all charged, all with good data transfer. BUT! There is a major downside in that when it gets hot and the fan kicks on, the fan goes on a crazy HOIL that pierces your eardrums and leaves sharp slivers of pain in your brain. And it's constant, so you question your sanity for a while and you think maybe you'll suddenly have tinnitus. But no, it's a hub fan.
