Thank you for resolving the delivery… Thank you for resolving the delivery issue with the portable concentrator battery. After the first one got lost in transit, you promptly sent a replacement, which works perfectly. I would recommend your company to anyone in need of oxygen therapy.

We ordered a Varon VP2 machine 10 days… We ordered a Varon VP2 machine. 10 days later, we received an NT2 machine, which is an older model. We tried calling. Mailbox full. We tried texting. No response. We tried email. No response. I am going to contact my credit card company. A 2023 press release states that the VP2 is a new model.

I bought a VARON New Arrival VT-1 3… I bought a VARON New Arrival VT-1 3 days ago. I have not received the VT-1 yet, but I have received the VH-3. The VH-3 is everything advertised and specified on the website. I have tested both flow and O2 concentration percentages and they match the specifications. I use the concentrator at night in conjunction with my Resmed AirCurve 10 ASV pap machine to mitigate central and sleep apnea and the VH-3 appears to be doing the job of helping to keep my SPO2 levels in the 90's as opposed to the mid 70's without. I have used a recording pulse oximeter overnight with both. The VH-3 replaces a large Phillips unit that is much bigger and noisier. I am looking forward to testing the VT-1 and using it while traveling. Please feel free to use this information, without identifying me

I purchased a concentrator I purchased a concentrator. It stopped working after 35 days. I contacted the company and they are only honoring a 30 day warrantee although they said it had a 1 year guarantee when I purchased it. One place on the web site states 30 days and another states 1 year. I may have to return it to the manufacturer in China, but right now Oxygensolve is giving zero support
