Not good.
I had tried these after using Afresh thinking they couldn't be that different, and oh, my, yes they were! You have to use numerous cleaning blocks to get it clean and then it only lasts for a week at most... I'm going back to the Afresh. Yes, I do not get as many but they clean and I do not have to do it again for over a month. Previous vinegar and baking soda cleanings were better than these tablets.
