A very useful and simple ball to insert into the washing machine drum. It provides the ideal amount of detergent for a medium load. It saves money on detergent and reduces environmental impact, while also better distribution for a more thorough wash and reducing the risk of unpleasant laundry odors. (Various videos online demonstrate the mistake of using the original washing machine dispenser, which wastes the detergent from the start. It also avoids using more detergent than necessary, with beneficial consequences.) You can even use two dispensers, one for the actual detergent and one for the delicate bleach.
An experimental ball compatible with the tops is included. The small spherical protrusions help improve washing and soften laundry fibers.
