I f I can persuade the thing to remain attached to my wife all day the results are very good, problems have been that the infusion needle (which has to be used in her lower back due to her very poor weight) seems reluctant to remain in place without an "X" of surgical quality tape (Durapore 1" wide is the best I've found), also I have found the tie-up between "flow rate" and the actual setting on the pump very confusing i.e for a flow rate of 4 the pump setting has to be .80 ml, the APO nurse has to carry a conversion chart!, I have made my own.
Also the connection between the infuser and the pump is prone to pull of as it is only a push fit, needs a screw thread!.
