I got the GrimmSpeed Master Cylinder Brace today.
The brace looks great. Very high quality (like all of GrimmSpeed's products). It is really beefy, and can take all of the brake stomping you can throw at it. The brace itself does exactly what you would expect. The brake goes from mushy and inconsistent to firm and repeatable. When you press on the brakes you get the feel you expect, and the stopping power you need. Very happy with it so far.
