      Wonderful 0 people found this helpful

      I found myself in a situation that would keep me away from home for a week after delivery date. Luke was absolutely fantastic and was able to get my new best friend delivered to my new destination the day I arrived there. He was fabulous and the G4 cannot be beat. I had to do a lot of walking and it was so easy. Thank you x 3

      Success after snags 6 people found this helpful

      After a rough and confusing beginning, I am pleased to compliment the company on their efforts to make a satisfied customer. The first G-4 concentrator stopped functioning a few days after I received it. I contacted the company and they immediately issued another. Unfortunately I had some issues with the 2nd one and that had to be returned as well. When I contacted the company to tell them there problems with the second concentrator, the employee sent a new one which arrived less than48 hours later. the staff was understanding and helpful. I am quite satisfied with the replacement and with the personnel. The concentrator is a good product and was easy to use. I am able to make and meet appointments offering me a new found freedom. Fran.

      Initially i wanted to purchase a new concentrator, but my timeframe did not fit the availability of a new one. The associate found a refurbished unit in stock that could be shipped quickly and this also saved me dollars. I am very happy with the unit and appreciate the help in getting what I needed in the time frame i needed..
