I have been using them for nearly a year and find them to work well generally, no problems with mud, etc. However they are not so good on sweat removal and I need to wash t-shirts with detergent every so often. Because of this my housemates have switched back to detergent. I’ve read on the ethical supermarket website (or somewhere) that poor performance might be because we have hard water and buying a magnoball (removes limescale) from the same supplier might help. I haven’t done this but might do as it will also mean that less detergent is needed and potentially be good for the machine? Although I’m not sure how good having 4 balls in there will be.
I also asked once if the ecoballs could be used with detergent. Apparently this wont damage them, although defeats the point!
