REALLY NICE METAL HOUSING, SEEMED GREAT QUALITY, BUT I COULDN'T FIGURE OUT HOW TO GET IT TO EXTEND MY DESKTOP... IT WAS EXTENDED FROM MY SURFACE TO THE MONITORS, BUT MONITORS WOULD ONLY SHOW EXACT DUPLICATE. :(
PROS: Works well. Thunderbolt compatibility is great.
CONS: It's a split output DVI device, meaning you will always get the same signal out of both DVI ports. We had purchased it hoping it would allow for an extended desktop across both outputs, in essence allowing you to have 2 external monitors from a laptop. It does not.
I was hoping to use this to connect three independent displays to a Mac Mini but it does not work that way. Should have read the fine print.
PROS: Allows you connect two DVI displays to a single Mini-display port
CONS: Only option for both displays is mirrored. You can extend your main desktop to the two displays but they will both display the same picture. Tested with Mid 2011 Mac mini and Late 2011 15-inch Macbook Pro
