Used new Dock to connect two monitors to my Dell laptop, both monitor work correctly. Tried cheaper brand Docks and one monitor would always flicker. I do get a warning when booting up my laptop each day that the C-charge port is to slow, but it doesn't seem to matter my laptop is charging and stays changed.
Works well with all of the Precision and Inspiron laptops in our office. Wish they hadn't discontinued the WD19TB model that included the 3.5mm audio jack, but otherwise, this dock does everything we need it to.
