I only have the pre-ban brakes, so I can't give you any hard info on how well the set-screws work, but the brakes themselves are real winners. They really work.
Ron Smith is a former Marine who shoots competitively and fully supports the RKBA. Once I bought at a gun show a brake that was represented as a Smith, but turned out to be a fake (wrong pitch on the threads, and the finish was just paint).
I called Ron just to let him know that someone was counterfeiting his goods, and he offered to send me a genuine brake for the cost of shipping if I would send him the fake so he could see it. Not many men will stand behind their product, even when it's not actually their product.
