Review on Enhance Your Furniture with Sauton's Folding Lift Up Top Table Mechanism Hardware Fitting Hinge: Gas Hydraulic Lift Up Table Mechanism (1 Pair) by Justin Bishop

They do what they are supposed to do which is lift the table top to keep it parallel to the floor. The problem I'm having is either because they're independent of each other, or because they're too far apart, causing them to twist when you count the vertex. The top can weigh 15-20 pounds and they do an excellent job of lifting and holding. My only concern is the advanced feature of lifting the table over and over again if the twist releases where it's secured and detaches/falls off. In my opinion, they probably wouldn't rotate as much if they were used for a small, maybe 0.75-1 inch thick board spaced about 12-18 inches apart, and you could possibly pick them up with one hand. Not for my use. I'll maybe try one of the more expensive ones with welded rods between the two mounts and see if that stops the twisting.
