I'd give it 5-stars if it was filled-in around the connector (cleaner look and easier to hit in the dark). Otherwise it was a great solution to cleanly put a USB charging jack on the front of my portable recording rig. I have lots of USB-A to USB-B cables about, so that connected me to a standard USB charger inside the rack. I already had another A-to-B adapter like this for the audio interface that is reversed, with the B-A cable on the inside going to the rack unit.
