Original 5 broke down on a cruise Original 5 broke down on a cruise, on/off switch failed. Disaster. Had to replace. New oxygenone regularly stops functioning. This a medical devise I am relying on. Can't. Be very careful before you buy one of these. Ps repairs to fist breakdown now been waiting 4 weeks still no machine. So 2 out of 2 not working.

Love this place, great price, great service Love this place! I've purchased 3 refurbished Invacare Perfecto2 V Oxygen Concentrators from them. (One for me, one for my wife, and one extra so we don't have to use both of them 24/7, we can switch off to the spare.) They're all great, had one for almost three years now, still reliably pumpin' out wonderful O2. Communicates quickly. Communication from company is good, packaging for ship is superb, price is right, what more could you ask for? Thank you for your excellent service, Oxygen Plus.

Fast friendly service Fast friendly service. They have always been responsive to my needs for over 8 years now! I rely and depend upon they to provide the euipment I need. They have always done so with the greatest of professionalism, trustworthiness and dependability. Thank you again and I will continue to look forward to our business and family like relationship.

Great concentrator Great concentrator, especially at the used price. It is very quiet, One negative- It generates the most heat of any concentrator I have ever used. Easy to compensate for during the winter, bur spring and summer are coming!

Oxygen Plus Oxygen Plus , got my machine delivered to me , with a slight delay , they were waiting for some out of stock extra filters for my machine to arrive that I also ordered at the same time . Oxygen Plus has some very good prices on their used concentrators. Thanks Oxygen Plus ;) David
