The Black Rapid BRAD MOD strap stabilizer is processed solid and not verutscht. But is very easy to move if you want to adjust it differently. Today I was the first time that the go and can only confirm that he is doing what he should - the shoulder of the Sun Sniper Pro stays where it belongs, on the shoulder. No move hassle and reset on the shoulder more.
It is not cheap but because it is solid and does what it promises - 5 stars. I can only recommend it.
