I use an in centre 5008s machine. It has all the bells and whistles on it! I self care so do fiddle about with it quite a bit. The HDF does seem to give better results. I find it better not to use the BTM on the machine though as can range your blood temperature from 35.5 to 37.5 during a session and I don't like that, If the nurse has lined it through the BTM I remove the lines and set to steady 36.5.
Any questions and here to help.
