Portable Oxygen Concentrator Creliver, 24h Continuous Oxygen Supply, 1-4L /min 90%~30% Adjustable with Anion Function, 45db Low Noise, Oxygen Generator for Home and Travel Car Use

The product was delivered the very next day and Thanks to Serena for the link sending the battery and the bag

Detachable water reservoir leaks any time it has water in it.It seems impossible to get a replacement water resrvoir so will have to return whole item.

I have purchased this product for my beloved Pomeranian who suffers from heart, kidney, liver conditions in addition to her chronic bronchitis. We have already had a home oxygen concentrator from Creliver for a month. Hence, we have known its superb excellence for customer service and products. Additional filters, a portable battery information, and a replacement product are all provided to me within a day. Without this product, it would have been impossible for us to take a mini holiday with our beloved Pomeranian. Highly recommended.

I bought this product for my husband who has COPD. It is amazing we’ll worth the money. I contacted the company by email as we wanted a battery and a backpack so it could be used outside. They responded straight away with a link for the battery and back back. Would highly recommend. Excellent customer service. Thank you so much Serena x

Is not useful for my patient with breathing difficulty.....I spent about 90 £ to return it and this too much for me ...please consider this

Good shopping experience, customer valued and treated fairly. Fast delivery, prompt communication, pleasure to do the business with. Strongly recommend.

Excellent product and after sales service. Highly recommended!

I was a little apprehensive at first. It was a lot of money to spend.I have used the oxygen concentrator for 2 months now and it has greatly improved my lifestyle.I suffer from COPD.I liked the oxygen arm that came with it and made enquiries to get a spare. The company responded favourably and above all promptly.Flawless so far.
