Purchased this to connect a Surface Pro 3 to two Dell displays, daisy chained. Get full resolution on the first display, but second display only gets 1024 X 768 resolution (it's native 1920 X 1080). Spent a lot of time trying to solve this issue changing drivers, updating firmware, etc. Removed this cable, replaced it with a 6' cable purchased from Monoprice at the same time - and presto, full resolution. DisplayPort is supposedly designed for runs up to 15 meters, but this cable apparently isn't.

PROS: Hard to say since I can't use it

CONS: Doesn't work in my application

it worked for 5 months then died. but for 8$ with a lifetime warranty i really have little cause for complaint.

I was trying to minimize the length of the run for the VGA cables on a MacBook mini-DP to Matrox triplehead2go mini-DP input (mini-DP in/3 VGA out). I had hoped that I could run two 15ft cables for 30 total, but it didn't even work with one. I don't know if this is a limitation of the DP physical interface, or if the triplehead2go is marginal. Since there seems to be no specification for how far you should be able to drive a DP signal down a cable (meeting certain cable specifications of course), it's probably going to be hit or miss what the maximum length of cable you can use for any given set up.
BTW, Matrox tech support was worthless I asked how long I could run the DP cable and got a reply that said they only test them with standard length VGA monitor cables.

PROS: Well, it's a mini-DP cable.

CONS: It didn't work for my application.

Using this cable with a DisplayPort to Mini-DisplayPort adapter to connect my PC with an ATI 4850 with DisplayPort to my iMac 27in with Mini-DisplayPort. Running the PC 15ft away from my iMac at 2560x1440 resolution. Image quality is great with the cable on the iMac. No setup issues. Great price and fast shipping with Monoprice.com!
