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!

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.

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.

Oxygen Plus Rebuttal In a response to the poor review I gave Oxygen Plus, they made false statements regarding the equipment I sent to them for purchase. They said it “reeked” of cigarette smoke which is totally untrue. Neither myself nor my late husband smoked. Further, anyone could inspect the package at this very moment and verify that there is no hint of cigarette smoke. Secondly, they said the smoke smell was probably the reason none of the other companies that I told them I contacted wanted it. I had no conversations whatsoever with Oxygen Plus about any topic. In my opinion, Oxygen Plus is trying to dilute a bad review by making me sound like a crackpot.

Life saver I was with a popular, much advertised company under Medicare. My large concentrator went out, but when I called they said my account had been closed two years prior. I could get no other information from them and nothing in writing. My doctor could get no information either. I was trying to make it with just a small portable. My home therapists finally told me I could purchase used equipment without a doctor's prescription. I compared several companies online that dealt in used equipment. Thank heavens I found your company. You were a life saver and I mean that literally. I was so oxygen deprived and weak that I was on the verge of being hospitalized. I can never thank you enough for the excellent equipment and your rapid delivery. I will keep doing business with you. God bless you all.
