I purchased a 10 liter oxygen…
I purchased a 10 liter oxygen concentrator a little over a year ago and it is failing today. I also purchased a 5 liter of the same Devilbis brand in November of 2025, and it died in January 2026. Two months of use, and under warranty and the company expects me to pay shipping to send a very heavy machine back to them and they said they will keep it up to 6 months for repairs. They only pay for shipping, even under warranty, within 30 days. If I didn't have a backup, I couldn't afford to not have the machine for six months. Now, the backup is going out. I've spent over $2000 on concentrators with them in just over a year and they were horrible customer service and now I might be without a concentrator. They are counting on people not wanting to pay to ship things back to them and they will be forced to buy a new one. The kicker is - I originally purchased another brand that I knew was reliable. They called me to convince me to change to the Devilbis brand. They claimed it was better, and the prices were about equal so I listened and switched. But they don't last long, and I think somehow they must get a kickback. Making it difficult to get repairs under warranty, even when the machine fails in an unreasonably short time makes this company a 1-star for me. Would not recommend. Don't waste your money. The machines are low quality.
