I've had the best results ever using these. Burnt on grease and food are no problem for these tablets. Glasses are gleaming, cutlety sparkling clean. im really impressed and it really does live up to the claim of cleaning your dishwasher too, no longer has a whiff between washes and the filter was clean. I have only knocked a star off because it is not ECO friendly and there is a bit of a trace of chemical smell and taster if you dont allow cups, plates etc to cool down before using straight from the machine.
