I have a couple of Neewer S brackets but had to upgrade to the S2 because I needed the round head capability. Even for non-round head flashes the S2 is superior because it doesn't have "teeth" in the tilting mechanism, so you can fine tune the tilt to whatever you want. The overall build quality is much improved. The one thing I liked better with the original bracket is that it has a screw in the umbrella shaft holder to hold the umbrella in position. The S2 dispenses with the screw and instead holds the umbrella shaft by friction, which sometimes makes the umbrella shaft a bit slower to insert and adjust. However, overall the S2 is a definite improvement.
