I've had two sets of these irons, one with DG R300 shafts and a second with the Lite version of the DG S300. All I can say is the shaft makes all the difference. The R300 set were awesome. Smooth, soft, forgiving iron. The sole cuts through turf like no other iron I've played. The other set....not so much. The feel was not the same. Try these out with different shafts if you can before buying.
This is a bad iron set. Don't buy it.
