how easy it is to save detergent

This is the third washing ball, which is in my application.
My first was about 4 years (2-person household) served us well, then noticeably lost its effect.
Therefore, this ball came as the successor to the house.

The washing ball is made of a flexible material and has no hard edges or corners dirty.
Filled is the RELAX DAYS Waschball with different colored balls. Surprising because the Erstkugel included only white balls.
The ball has a slight "fragrance fresh" smell, even if no perfume is indicated as a component.
Although the washing ball is used with me with some washing powder, I do not think that what carries the scent of balls on the laundry. If it is, it smells fresh at least ;-)

Meanwhile, the first three machines are running with the ball and wash as previously reaches one-third of the recommended amount of detergent and the laundry is still clean.
Perhaps it would also (almost) without detergent, but I feel so comfortable and the laundry smells simply fresh ...

Parallel I have the "green purclean Waschball" ordered, this is hard plastic material also contains multi-colored balls and smells slightly. This has only received 4 stars from me because of the plastic.
