I needed another 02 concentrator for use in the den since moving the other one from bedroom to the den and back every day was getting to be more than I could manage. I found wellue to be reasonably priced and unit is not as heavy as some others I looked at. I am happy with the unit and I am looking at a small portable for when I go out. Thanks wellue.
