I purchased from Luns 2 ceramic cartridges and wish to replace them in my Blanco Strand tap although I am having problems undoing the two screws either side holding the leavers on the splines. The screws do not seem to be normal Posidrive heads, does anybody know what they are and what screw driver is needed.

On mine they were quite difficult to remove but they are cross head and I eventually used a typical Phillips type screwdriver

What cartridges did you buy? I am trying to source some.
