"Folks, just a short note to express my appreciation for all the help provided to me by US Oxygen Sales in searching for, finding, acquiring, and setting up my new SimplyGo Mini (To me, it is superior to the Inogen One G3 which I also own). They have proven to be knowledgeable, readily available to answer questions, friendly, and an asset to their customers. On a scale of One to Ten, I would give them a Ten- (Why the minus? Because no one is perfect though they come close.)" - Jim W.
“I just wanted to let you know that my mom is very happy with the Activox 4L we purchased from you a couple of weeks ago. It certainly does give her more freedom with the long battery life and ease of use! I think it has helped her mental attitude knowing that she is not so limited as she was with the other system. Thanks for all your help, and for getting it to us overnight” – Nancy B.
“I have been meaning to write this letter for weeks. I purchased a Simply Go Mini for my mother at the end of August. I just want to express my sincere appreciation for the staff at US Oxygen. You have been so helpful, patient, and gracious during my interactions with you. At no point did I ever feel that you were just trying to sell a product. You answered all my questions so thoroughly as I tried to learn how portable oxygen therapy works. Thank you for the honesty and integrity displayed by the US Oxygen staff.  – Carolyn R.
“I have been using the POC for 2 days now. It’s exactly what I needed for this trip to be succsessfull. Thank you so much for all you help and for getting this unit and the battery’s to me on time. Once I get there I’ll try to send you a picture of me up in the jungle surrounded by the children of the village. Maybe someday you will get there too. It’s a beautiful place with beautiful friendly, kind people.” – Dan P.
“I received my SimplyGo unit today and it works great. The ultra sensitive pulse setting is wonderful with my shallow breathing. It picks up my shallow breathing with ease. Now I’m receiving the true 4 liters I require. You were right. This unit looks brand new. I can’t tell it’s refurbished at all. The AC/DC power chords are new as well as the ultra light and durable cart. Thanks so much for changing my life! God Bless…” – Bruce L.
