Kacsoo Newest Portable Oxygen Concentrator Generator 1-7L/min Adjustable Oxygen Machine Home 35%-90% High Purity for Home Travel Car Use (105W)

I bought this to assist breathing following after effects of Covid-19. It has proved it's worth night after night. I was having some difficulty breathing and consequently sleeping. Quite unpleasant. Using this equipment has made a great difference. The nasal supply tube fits easily around the back of the head and under your nostrils. It's simpler than it sounds. Unobtrusive.yet having plenty of length, the fine oxygen supply tube doesn't get in the way of my sleep position, even when turning over. it allows me to inhale concentrated oxygen while hardly being aware of its presence. It has 7 levels of concentrated oxygen it can supply, ranging from 30% to 90%. The higher concentration you select the lower the litres/min supplied. Personally I sleep with the 90% setting, supplied at 1 litre per minute.You can set the timer to supply oxygen from 30 mins - 4hrs (in 30 min increments) before it automatically switches itself off. Alternatively you can leave it set to continuous and it will stay operational until you turn it off.I love this kit, it's made a big difference to me. One thing to note, the instruction book is rubbish. Clearly written by someone not fully conversant with technical english. Fortunately, apart from figuring out how to use the mains adaptor supplied, the rest was easy to set up in minutes. On that note the mains adaptor is cheap crap, not at all in keeping with the main unit which looks great and has an LED illuminated, excellent control panel.The unit was almost whisper quiet in operation when it was first used. Since then it's got a bit noisier but not significantly so. Overall love the kit, glad I bought it.Hope this info is of use to someone.

I received the oxygen generator. Set it up using my own initiative, because the instruction book did not make any sense. Why?? Because whoever translated the operating instructions in the book supplied should have learned English before attempting to translate it.The method used to take out the water cup from the generator leaves a lot be desired. It would not take a genius to design a small ring handle for this job, instead of a small round knob which is so small that it has hardly enough room on it to grip.The generator itself is good. I have no complaints with that. It works very well. But there has not been a lot of thought put into the external design.

Good little unit easy to operate.Not the best thing to find the power switch on the back hanging out. Checked the connections and pushed back in.The face mask supplied is for a small child and totally useless for an adult. Will need to buy a replacement mask.Operation is quiet and oxygen output sufficient for this type of unit.Will see how it goes and update accordinglyPresence of oxygen tested using scientific means.

I would recommend it to my friends who need it, and let them buy it too. This is very nice, I like it.
