Good bang for the buck
I bought an oxygen concentrator from ehealthy. The unit arrived in excellent shape, was easy to set up and works well. Ehealthy has been great to work with (so far). I already have an "industry leader" upstairs so, I am familiar with the set up and operation of this type of unit. The Dedakj concentrator has several features that the other one does not and costs about a third as much. Time will tell if this unit will provide similar service.
