I briefly mentioned these in a posting in the laundry forum, particularly the phenomenon of excess foaming in my Bosch.
I tested them further, in a full-size Hotpoint FDW20. The load was normally soiled, but they produced far too many suds; so much so that the upper spray arm stopped turning.
If they were used in a poorly designed machine, there could be serious problems.
My advice is to stay clear of these, and stick to the well known brands.
