Perfect and fast delivery. The tablet fits exactly into the intended cleaning application of rubber. After automatic cleaning (about 5 minutes) was the tablet whole aufgelöst.Über the Effizenz cleaning I can not make well-founded statements as Esspressomaschine is new. Even a comparison with other purification tablets I can not offer, I assume, however, that the chemical elements are identical or very similar. An outstanding price-performance ratio.
