If I shake the table the cover wiggles a little but does not appear to want to close. It feels like it takes about a 1/2 lb of force to pull down. It is pretty close to vertical so there is not much force on the springs when fully open. It pushes itself open for about the last 2-3 inches. All other positions it wants to close. I was mostly interested in having it hold itself open and assist me in opening. The spring is available in 15, 20, 30, 40, 50, 60, 90, 120 pressures. I chose the lightest one.
There is a lot of adjustment capability because everything is mounted to the slots. I did not play with it too much. If it tended to close by itself, I could increase the support angle a bit. The nice thing about gas springs is that they keep a constant force throughout the compression, unlike a spring which increases.
