Review on Surface DisplayPort Gigabit Ethernet Microsoft by Shane Solorzano

A few days later I gave a 3 star review. However, after using the item several times, it became absolute junk. I plugged it in before booting Surface Pro 4 and sometimes it worked. More and more often it did NOT work at boot. Sometimes reconnecting and/or restarting made it work. But that also happened less and less the longer I used it. I would not recommend anyone to buy it for a Surface Pro 4 system. I haven't thrown it away [yet], but it won't be for long.
