After studying various precursor reviews I opted for this sticker. Important is a good pre-cleaning the shower / bath with corresponding commercial bathroom cleaners, after drying the surface cleaned again I with pure alcohol of any fatty residues. Since I have glued offset the sticker slightly narrower than recommended and rhomboid I need 60 pieces for an area of 60 cm to 50 cm. I have when bonding the sticker with a multi-folded soft cloth from the inside out "festgeklopft". You are now in use for a month and have proven themselves well (no more slipping in the shower, not even with lather!), Separation phenomena have not yet occurred.
