I haven't personally tried any Six Star products, but if you want a creatine product I agree with Eric that there are better options.

I stay away from the "designer" creatines that have extra stuff thrown in it simply because that usually means they are upping the price and lowering the actual servings of creatine per container. Just go out and buy some bulk CEE (creatine ethyl ester) or some mono, both options are really cheap.
