GBVery Pleased With The Oxygen Concentrator Store I was already thinking about buying a spare concentrator when you called and offered me a closeout reconditioned one. It was a very good price, so I was glad to buy it that day. I have only used your company for 7 years now for my concentrator needs and have had great service from everyone I have talked to.

GBFast & Efficient I needed a small used battery for my Inogen G5 portable unit. Found one here. Checkout was fast and efficient, and shipping was pretty quick, too. No complaints from me.
