From my hospital bed at the Calvary I want to advise others that CLM request a $50 fee to have the Sleep Test Equipment returned to them. The average courier price is $10-15 and ZOOM2YOU can do a 3 hour delivery for $18 (Pick up from your Hospital Ward easy online booking system). How can CLM SLEEP justify a $50 charge? After all they charge you $50 when they send the unit and a technician to wire you up. I am sure no such 'expertice' is required when they pick it up. In my opinion it looks like a blatant 'Rip Off'. NOT IMPRESSED !!
