DEDAKJ DDT-1A O2 Machine 1-6L/min POC Concentrator Device Humidifier AC110V (NO Battery)

The machine appears to really be a great machine for those of us that require oxygen but the instructions tell you nothing. The instructions need to be simplified and much more complete. I feel like I would get a lot more benefit from the machine if I understood its functions better. The only fault I have found with the machine is the oxygen nozzle needs to better fit the commonly available plastic tubing or at least furnish an adapter to the regular tubing.

This machine is pretty easy to use. The only down side is that there are some extra pieces that I don’t know what to do with. I have a number of autoimmune diseases which translates into a lot of fatigue and brain fog. The extra oxygen helps me recover more quickly from exertion (like sitting up or walking to the kitchen).I’ve been using this for 2 days and already notice a difference. My O2 sat was 89 yesterday morning. After a few minutes with oxygen I was up to 98 and doing good.

very nice product and easy to use and set up

I wish I could give you 4 or 5 more stars!! Brought my concentrator to New York, in a suitcase, on the train. Set it up in 5 minutes. Slept in the same room. My regular machine is in another room, 15+ feet away, heard clearly in my bedroom. Love this little whisperer!

Very disappointed! In the pictures the machine is shown to be in English but when we got the machine it was all in Chinese.

Instruction manual leaves something to be desired but most of it you can figure out. First few nights (night use only) everything worked fine. Was quiet and functioned properly. The third night I noticed a muffled chirping sound from the unit. Not sure how to describe it better. It is just audible and I am hoping it goes away. I will re address this in several weeks if sound still present.

 I was looking for an oxygen machine for home use because of my father in law has cancer. He has problem breather most of the time, so I did some search. I can cross this machine from Amazon and was hesitated to purchase a $300+ machine. After a week of using it, he said it really helps and give him the oxygen he needs. The oxygen machine is well made and little heavy. Super easy to use, just like plug and play, but please read the manual and follow the instruction. It got a LED display all the information on reading and it comes with remote too. At the end, it helps my father in law breathing. Great purchased.

Works easy to use
