My wife's nebulizer inhaler and connective tubing stopped working. I called for an appointment, and Patrick in the DelRay Beach Lincare Customer Service office opened the door and invited me in. He was extremely polite, and carefully demonstrated how to assemble the 4 piece section where the albuterol drops are inserted. He showed me where to insert the tubing that connects the inhaler to the Nebulizer Machine. There was no charge for this consultation, and Patrick couldn't have been nicer. I would highly recommend this Service Technician.
