I bought some white plastic caps from B&Q, used to cover the screws
that hold the toilet down to the floor. You know, a cup-shaped washer
and a cap that snaps on the top. I tightened the screws down through
the cup section and thought "job nearly done" and got ready to snap
the tops in place. Trying this, the useless things just rattled around
on top, clearly being nowhere near tolerance. Blue-tak was required to
hold them down. Very poor quality indeed. I shall be taking the others
back for a refund and complaint.
