THERE WERE PROBLEMS....!
-Ordering the concentrator went very smoothly. -The item arrived as scheduled; unfortunately the item arrived without the 2 batteries as listed in the package. This made the concentrator unusable. Also unfortunately, the first rep. I talked to on your end thought I was only supposed to receive 1 battery; of course 1 battery is better than 0 batteries. - When I finally talked to a knowledgeable person things went quickly. The batteries arrived and I was able to use the concentrator. - I am happy ! - Also I very much the breathing issues booklet that was included in the concentrator package.
