I bought a oxygen Concentrator from… I bought a oxygen Concentrator from them but there was no owners manual so I emailed them they said look in your junk mail I did no owners manual so I emailed them again an this time I didn't get a answer.I am pretty mush dissatisfied with there customer service.

Oxygen Plus is a pleasure to deal with Oxygen Plus is a pleasure to deal with! Conversations with the owner were informative. The service was extraordinary. I would recommend this business to anyone with oxygen needs. I might add that this was my second experience with Oxygen Plus. More than five years ago I purchased a refurbished concentrator that is still going strong. The portable concentrator I bought this time is efficient and easy to operate.

I FIRST BOUGHT A USED CONCENTRATOR FROM… I FIRST BOUGHT A USED CONCENTRATOR FROM THEM WORKED GREAT THEN I HAD A ISSUE THEY TRIED TO HELP OVER THE PHONE GOT IT WORKING THEN THEY SENT A REPLACEMENT AND A FREE PICK UP OF THE OLD ONE.JUST RECENTLY ORDERED FILTERS AND THEY ARRIVED IN A COUPLE DAYS.

Communication could have been better Communication could have been better. Original item ordered was no longer in stock. Another model was supplied but had to call them to find out what was holding up shipment. Am pleased with item received.

Not great The machine will only go to 4.5ml. the alarm does not sound. It is making a funny noise after just a couple weeks. When I called customer service he said the alarm was not important and if it doesn't sound after a couple more uses call back.
