I have several, and I've shot probably north of 15k rounds through them. I like them. They definitely adjust the gas. Depending on barrel length, port size, buffer weight, and spring strength I have found, especially as of recently, that the adjustment gradations are not fine enough. I wish it had a more "linear" feel to it (possibly not actually linear, but my point is that the adjustment to the weapon behavior seems to jump by large amounts even for small adjustments) and or maybe another setting or two (5 or 6 positions total), but not more settings on the extreme ends of the adjustment, like I said just more gradation.
