I've gone through at least two docks before and it has the best features so far. It has three USB ports, a 3.5mm audio input and output, a power button, an Ethernet port and two HDMI ports. The power adapter for the docking station charges the laptop when it is plugged in. It's also surprisingly light. The DisplayLink software was pretty easy to use to get external displays working. The first dock I had only had 2 USB-A ports, which was pretty basic. It's enough for the devices I have; Therefore, a USB hub must be purchased. The second dock had a number of USB ports; However, it only worked for a month and stopped working. Customer service was bad too. Not sure if it's worth $159 but I hope it will last as I just received it yesterday.
