Fantastic Folks, Service and Products at OxygenPlus Concentrators. Their turnaround for servicing our Millennium M10 02 concentrators was fast and thorough. Our EWOT systems are chugging along good as new. And we're happy campers as a result. Mark "Mr Noots" Effinger BiOptimizers.com

It was great. They originally made a mistake and missed an item. I emailed them and within a few hours they were sending me the missing item. All items order are good quality.

Helpful staff & technicians. Fast shipping and reliable performing oxygen concentrators. Reasonably priced reconditioned concentrators that appeared new when examined after receiving my order. I'll definitely do business with them in the future.

Equipment came in a timely manner and works great so far.

I guess it is generating oxygen - there is no way to tell but it has a loud rattle that is really hard to sleep with sometimes.
