As a non-musician, I used this "Pow-R Rack USB AC Power Center" as a pdu in an HPE server rack to control other accessories in the rack like LED lighting inside the rack, to power on/off power to LCD screen/console, and to control fans inside the rack. This strategic use of this device allowed me excellent flexibility to control my accessories very efficient. The quality and craftsmanship of this device is "excellent", especially the control buttons have really "smooth" and quality feel as you press on them on/off. Also, I really liked the "dark green" LED's on each button that perfectly match the color scheme of the HPE rack of black and green. Overall, an "excellent" with no known bad issues......highly recommended.
