Hi, this is what I found on Youtube.  I have ordered two of them and will try.  The reviews are positive, but not sure if these are promotions or real reviews.  It sounds to good to be true.  Therefor a real test !  As soon tested, I will share my experience.  If it would be true, it would reduce enormous amounts of chemical and plastic waste !

After ordering the Terra Wash, the product was delivered one day later ! Wonderfull, and this for 49 euro.
I used it a couple of time till now and sofar, it does what it should do.   The bag is of cotton, containing the magnesium granulate.   The durabilty still has to be proven, whether 365 times reusable.  It is certainly worth the investment to try !
Eliminating the phosphate into the drainage is certainly good for the environment !

I will continue to use it.
