Recieved Oxygen concentrator 7 days… Recieved Oxygen concentrator 7 days from order. Machine operates great. I have used it for nearly 48 hours without incident. Remote control unit isn't operating but have not yet contacted company. Pleased with concentrator plan on using on vacation travel, it's about 1/3 the size and the weight of my medical supplied unit.

So happy with my purchase! I am extremely pleased with my purchase. The device works excellently, offering around one hour of usage on a single charge and taking approximately one hour to recharge. It is also lightweight and easy to carry. As a resident of Alberta, Canada, I received my order within nine days, which was quite impressive. To summarize, my experience with the oxygen concentrator has been fantastic, as it arrived promptly and has been functioning exceptionally well.

I purchased one of their units and O boy what a ripoff I purchased one of their units, after I received it I tried it and realized it was not going to work for me. Since the unit had a 30 day return policy for a full refund, I started trying to call their listed customer service number and found out later in an email that their phone number wasn't working! Then after 9 emails they finally gave me a Rma number and the shipping address that was in China I attached a label and took to UPS where I was told it would cost 400 to 500 dollars to ship it to China which exceeded the purchase price of 351.10. So it's a ripoff if you ever need to return it for credit or service!! What a rip-off!!! BUYERS BEWARE !!

Great Shopping expercience, Well worth the money As someone who relies on oxygen therapy, I can't express how grateful I am for the Portable Oxygen Concentrator NT02 from Oxygensolve. This 5L oxygen concentrator with dual mode functionality has truly been a game-changer for me. The oxygen concentration of 93% ±3% has helped maintain my blood oxygen levels consistently at 95%-96%, giving me peace of mind about my respiratory health. Additionally, I opted to purchase the large battery, and it has been a lifesaver when I'm out and about in town or at the mall. I no longer have to worry about the battery running out, allowing me to enjoy my outings without any interruptions. Thank you, oxygensolve, for providing a reliable and efficient solution for my oxygen therapy needs. This product has truly made a difference in my daily life.

Ordered an oxygen concentrator it was… Ordered an oxygen concentrator it was dead out of the box. I contacted them and just got run thru the bushes. Illogical questions, nonsense videos, the damn thing won't start. Finally went to Pay-Pal, they said no problem just send it back to China ($410.00) and they would refund my $285.00. I'll talley this one up to experience. What a bunch of confused turkeys. Yes I'll include Pay-Pal. They offered absolutely no protection. Do yourself a favor an deal with Amazon.
