I'm a new dishwasher owner and not really well-read about these machines and how to use them properly. I complained about a few broken tablets to the staff, and they promised to replace them on my next order. However, they did tell me that there's really no major issue with using them. I was advised to continue using them, observe the results and let them know how things go. After more than 8 loadings, I really could not tell any difference between using whole and broken tablets. Amazingly friendly staff at Akiba, and very knowledgeable at that. Thank you!
