Reviews
I’m impressed. This cistern block really lasts much longer than others I’ve tried - it's been longer than a month and it still foams and runs blue. The toilet bowl also stays cleaner and fresher for longer—even during water interruptions. It gives me peace of mind knowing that it’s safe for the environment.
Dit hou die toilette skoon en vars en dit is lekker om te weet dat dit nie besoedeling sal veroorsaak nie. My blok het net twee weke gehou en nie 'n maand nie - dit kan dalk wees as gevolg van my groot cisterns en ook dat dit baie gebruik word. Ek het met kliëntediens gepraat en hulle het voorgestel om ’n groterige gaatjie in die sakkie te sny en dit so in die cistern te los - ek sal definitief volgende keer dit probeer.
