Recently bought a washing machine.

I looked at Miele, saw the requirement for using their refill containers (TwinDos†). Noticed an option for using not theirs as a fallback but it all seemed a bit convoluted.

Then I took a look at some high-ish end LG and they had sort of the same principle (EZDispense††), except the dispenser sits like a usual tray that you fill in with regular off-the-shelf liquid stuff, and then you're good for a while. The whole wifi/app stuff is entirely optional, the machine is fully functional through the panel without the app. So I got that one, very happy so far.
