can anyone please advice how long these should last? Obviously dependent on use and loads but I had a damaged machine delivered from day 1 but could use it, so I filled both detergent and softener and was surprised they lasted over a month. Had the replacement delivered only last Tuesday so not even a week and again filled up and softener is showing low after 6 days and we’ve used it the same 5/6 times a week and in settings softener is in x1. so was the 1st one not dispensing properly or this one too much. What are you guys getting typically?
