I picked up the EC tuner brake also. I really like it. I put it on my Tikka 7mag Roughtech. I've told my friends it's the only brake I'll buy now. It's a well engineered brake to begin with, and offers the option of effective tuning for the same price as a good brake with no tuner. When funds allow, I plan on getting a few more, I have a 6 creed that I'm working on as the time/cash permits, and I'd also like to try one on my 338 Norma. I already have a Terminator brake that works awesome on it, but I'd like to experiment with different bullet weights/types, and see how the tuner works for those.
