5 out of 5 eggsExcellent product

Pros: - Rock solid FTDI chipset (the competing PL2303 is garbage)
- Well-built, easily rack-mountable
- Indicator lights help identify which systems are talking

Cons: When I connected this to a Linux machine, the ports order is different between the /dev/ttyUSBX numbering and the numbering of the LEDs:
Port 1: /dev/ttyUSB1
Port 2: /dev/ttyUSB0
Port 3: /dev/ttyUSB3
Port 4: /dev/ttyUSB2

Other Thoughts: ttywatch is an excellent piece of software to use with this device. It allows you to expose a port via telnet, and also allows you to log all data sent to/from the port.
