Apply appropriate vertical pressure and one to two rotations of the cap will be sufficient. In competing devices the need of multiple rotation of the cap of the device makes the process of installation of tiles extremely long.
When leveling the tiles Superleveller does not make the tiles rotate, which is extremely important once the tiles are laid on fresh adhesive. All other devices present shearing issues when turning the device around the axis when trying to bring the tiles to the same level: the tiles get pressed against the fresh adhesive and they tend to warp.
Spacers are located on the base of the device, not on the strip which makes them fully visible even after positioning the device to the tiles.
