Portable Oxygen Concentrator Machine, Oxygen Concentrator for Home Use, Help Health,Oxygen Tubing, Can Remote Control

When I got this, I saw the reviews that said it's not portable. I didn't let that affect my decision, because I didn't need it to be Portable. But I wish I had waited a little bit before ordering, because a couple days after I did, a person reviewed it saying it only lasts for 3 hours... And they're absolutely right! >:( Whats the point of an oxygen machine that lasts such a short time??? They were also right about the stream not being consistent. INCREDIBLY annoying. Lastly, the whole thing just FEELS cheap; like it's sponge to break much sooner than later. If I could give it zero stars, I would.

Better than expected, considering a second one. Highly recommended

Yes a meager 3 hours or 180 minutes. In addition, its output is hardly 2 liters, and it buffers the output so it is not a steady stream. The stream is modulated which is really annoying. End of the discussion, I am sending it back. The listing is not accurate, and I should not have to find out the problems after it arrives.Also, the item was returned and the seller has yet to issue a refund. So as far as I can tell this is a dishonest company!

Nothing was available from Amazon about the mfg warranty before purchase (WHY?), and NOTHING about any warranty COMES WITH THE UNIT !! ( Again, WHY?) Be smart and buy the extended 3-year warranty cuz you're going to NEED IT ! The last O2 concentrator (styled just like this one - The one I bought last year is no longer being sold-wonder why) only ran just over 4,000 hrs, (13 months) then it quit ! If I hadn't bought the ext warranty I would have been out the $469. I did, however, loose the cost of ext warranty and sales tax. Return shipping was covered by Asurion warranty. BE SMART, BUY THE ASURION WARRANTY !!

This product is not good at all, there are better brands out there that I will look into. The lack of oxygen concentration, it does not meet my needs after multiple test and comparisons with different brands. v:AY_Nuyoah7

I expected the size to be a bit smaller as it is made for portability in mind. It has too many components that are easily displaceable and does not fit in my hand carry baggage.

Was missing some of the important parts so did not work for me. Would not buy again

This is bulky and heavy. It is not portable at all. It also puts off a really strong odor when using. This definitely will not work for me. I purchased a different style and am returning this one.
