I have recently bought the Photo Master Stand, Air Cushioned (1004). I find it really nice. However, as it is my first light stand, there seem to be something I am failing to understand: I was under the impression that air cushioned means that even with a flash or other heavy equipment mounted on the stand, in case of emergency, the pole will descend slowly down and keep the gear safe (demonstrated in this video: https://youtu.be/xIM7TYpYFr4?t=20s). However, when checking this mechanism (under close supervision), I noticed that if I will open one of the locks slightly and let the pole slide down, it will not go down slowly and safely, but very quickly and not cushioned at all. Am I missing something or doing something wrong? Is it possible that I got a defective unit?
I appreciate your help!
