I absolutely do not recommend buying these anti-limestone pellets. But given the price, one would expect a good performance, it is not so! The chip does not melt completely during washing (whether long or short wash, hot or cold), and I found whole pieces, or large powder residue on clothes. Then used according to instructions by inserting them into the tray "laundry" is even worse, the chip does not melt at all, and it leaves a thick paste into the detergent box. I never had this problem with private label pellets.
