VA Compensator

[Reeyah]

I stumbled upon a compensator that claims zero muzzle rise... As with anything that sounds too good to be true, I do research before throwing money (what little I have) around. This is the link off of a person from a different forums sig http://www.bp-tec.com/ Does anyone know anything about this particular break. I know how breaks work so I don't need anyone to explain them, but I want to know if anyone has experience with this particular break. They claim zero increase in noise with this brake. The only explanation for this would be that it vents up rather than sideways so unless you are standing above the barrel the noise increase associated with the redirected gas might not be noticeable. Note: the videos on the site show impressive reductions in muzzle rise, but they may not be 100% real. For example: they may be using reduced recoil rounds when they show the brake on. Please if you know anything about this leave a comment.
