We had our WH FL when these came out. We even received two tablets in a little box in the mail! The coupons at that time made them almost free. A full load in the Westinghouse took only one tablet and a small load took a half a tablet in our soft water. Out water heater was set to 160F, which you could do then and the washer was close to it so out whites were brilliant. We had boxes on the shelf, all bought on sale with coupons. They broke in half easily and did not crumble to dust. Rinsing was good, also. It seems we used these for quite a while. I don't know why they were discontinued. Maybe with all the promotions, P&G never made money on them. We used a lot of VIM also. We went back to Dash after SALVO.
