excellent machine
I have now been using this machine every day for the last month and would highly recommend it to those like myself who suffer from quite severe COPD although its capable of running 24/7 I use it about 4 hours a day and at night setting the timer to cut off after 2 hours I have found that I am sleeping better and breathing easier it is very easy to set up and operate and adjust to your own personal needs.

Very good and efficient device. It’s very easy to use and easy to follow the instructions provided. Oxygen purity up to 90% which is tremendous. It’s fitted well with different types of filters do there is no worry of the purity of the oxygen receive which is very reassuring.

Good quality unit. Company very helpful too.
It’s slightly louder than I thought but all in all a great buy. Easy to use and nicely designed ?
I am very glad I ordered one.

I recently purchased this Oxygen Concentrator and I couldn't be happier with my purchase. Not only did it arrive the very next day, but it has greatly improved my breathing and overall well-being. The machine is easy to use and provides a steady flow of oxygen at the level I need. I highly recommend this product to anyone who suffers from a respiratory illness or has been impacted by Covid-19. The machine is a game changer and I'm so grateful to have it in my life.

I find the device very good so far, it is easy to use and cleaning/changing the water is simple. At night, the volume was not very annoying, you got used to it quickly. So far, I'm very satisfied

So far absolutely brilliant. I have COPD and suffer with severe tiredness, motivation, and all the other breathing problems associated with COPD. After being told I needed oxygen at home I was told it would be at least 3 months wait! Out of sheer desperation to get some kind of quality of life back, from basically vertualy bed ridden I thought I had nothing to loose in giving this machine a go. It's only been 48 hours, but already I feel more alert and with it, and can breathe much more easily, and can walk small distances.
