Review on Screw In Stabilizers - Gold Plated, Green PCB, Transparent PC Material - Mechanical Keyboard Accessories with Satellite Switch - 6 Inch by Brent Porter

Looks like old Durock stabilizers so I decided to give them a try. For the price they are not bad. Definitely better than clips. However the cases are slightly yellowish (I bought the clear ones) and two had clips broken against the screw hole and could not be used. Definitely not bad for the price if you want to save some money on your build but I wouldn't expect them to be as good as the Duroc shocks.
