I have been using it for last two months. I have to say that i regret to bought this instead of WSP.
It hurts my hand everytime when i try to tighten the knob for 90 or 110 degree. Why they so stupid using knob instead of like WSP style? If I don't tight enough, the vertical bar will move up and down like crazy cause the knob is not able to lock in position. And also, I have to try multiple times to move the vertical bar up and down little by little to locate the stupid 90 or 110 degree hole.
