Detergent coating was effective to reduce electrostatic charge, and to increase dose delivery, but had no effect on dose variability. Bad cooperation was an important cause for high dose variability for all spacers (r=0.5-0.6, p<0.02). Many mistakes were made during the administration procedure. ER -
