Original 5 broke down on a cruise
Original 5 broke down on a cruise, on/off switch failed. Disaster. Had to replace. New oxygenone regularly stops functioning. This a medical devise I am relying on. Can't. Be very careful before you buy one of these. Ps repairs to fist breakdown now been waiting 4 weeks still no machine. So 2 out of 2 not working.
