We were excited to see your Black… We were excited to see your Black Friday sale for the Reconditioned Everflo. Being on Social Security, we cannot afford a new oxygen concentrator and really needed one that would work. I would have given 5 stars, but the shipping was slow. Probably you got more sales than expected, but we were fortunate that a neighbor let us borrow her mother's, who was away for the holiday. The reconditioned Everflo works like a charm. I actually was able to set it at a lower level lpm that I was able to do with the used machine we had gotten from a local medical recycling service (which only lasted 6 months.) Thank you for being there and your discounted prices.
