Review on RSHTECH 7-Port USB 3.0 Hub Expander with Universal 5V AC Adapter, Individual On/Off Switches, and Aluminum Data Port - USB Splitter for Laptop and PC (Black) by Mike Martz

Looks good and feels good enough. But every time I plugged it into the power adapter, some of the electronic devices connected to my computer would turn on, for example the LEDs that I connected via USB would go on and off every few seconds even when the computer was on. out. Update: After returning the product, the company contacted me and sent a replacement to test. The new device has worked well and has not caused any electrical problems in my setup so far. Everything seems to be working fine now, but due to initial issues I can't downgrade my rating to 5 stars.
