OMG oxygen concentrators
 

Does anyone have any experience using an OMG Evolution, Revolution or Magnum concentrator/generator? I'm wondering how long the units last, repair tendencies and how close the actual PSI and LPM are to advertised PSI and LPM. I'm wanting to fully power my GTT Phantom. OK to spend the money, just want something that is reliable and works.

I think they're new enough to the market that nobody's had one for more than a year. Here's the best info I've found about them: http://www.talkglass.com/forum/showt...ht=#post901463
