Works as expected (!) with no serious surprises.
Cons - low profile bracket. Had to buy a high profile bracket for $14 elsewhere. Windows doesn't have a driver for the Intel chip set. Won't work with Cisco SFP+ fiber adapters.
Pros - works very well with HP SFP+ adapters, dual 10gb ethernet. Intel PROSet configuration works well and is free. Driver from Intel works on Win/10 with no problems.
