Basically, I bought this pad to replace the very poor directional think the DualShock 3, having been too used to "clicking" PS Vita which in my opinion is much better, although obviously smaller. So without equaling the latter, the D-Pad FC4 is very correct and offers a good touch. The DP leave alone and the rest of manipulations poses no problem even if I did not note any improvement in my performance / accuracy is more pleasant to play on.
I have not had the opportunity to serve me a lot of two additional buttons on the face, but I can see the potential it offers for specific games. And as was said in another post, no problem to plug any PC (no more than a DS3 and DS4).
Besides, it is convenient that this model offers a PS4 compatibility, it will avoid to buy when make the leap to the next generation. It can help justify the price (although I board still trying to find around 40 if possible).
