Review on Lenovo ThinkPad Thunderbolt 3 Dock Gen 2 (135W) (40AN0135US) + SSD Starter Bundle: Enhanced Connectivity and Storage Solution by Bill Pulse

Right out of the box I had trouble charging the device from a Lenovo PC. I had to keep using the portable charger in the extra USB-C port. Also, intermittent advanced monitor detection occurs which annoyingly resets the monitor and PC displays. I spent an hour on the phone with Lenovo support without doing anything other than reading queue cards or moving you to another department. Keep in mind that this was after the first hour I spent verifying the right dock model for my computer before I bought it. I recommend HP. Drop Lenovo.
