Summary: This unit delivers what LG claims. It can work with one usb, read and write CD and DVDs.
Pros: Very light and stylish. Average speed is above my expectation for such small and low power device.
Cons: Although it works with one USB, it will not work aways. You must have a full compliant USB port, some ports have low power. With low power USB port the unit can refuse to work, so is tricky to find the correct USB port.
