  • haven't used yet

    I am using the nose O2 and seems to be fine. The green tubing I will use when the one I have now wears out. I hope it will not tangle as much as my current white one.

  • Tubing OK but had many crimps

    The 50' ft of green tubing had numerous points where it was "crimped". I had to stretch it out straight for a couple of days before it opened up enough to flow freely.

  • Tubing

    I bought this tubing for my mom, so she could have more mobile room around her house. The length is great for what she needed. It was good for a short while, but the tubing kept tangling, twisting, and kinking up. She got so frustrated with it, she took it off and went back to her old tubing. Would not recommend this.

  • Good product, great price and fast shipping

    I was very pleased when I received my order, arrived promptly and product was what they claimed it was. I have been using this same brand tubing for the past year and so far so good. Also can't beat the price. Thanks cpapxchange for your professional service!

  • Fast Service

    I am new to C-Pap and wanted to purchase a back-up 50' tubing. I found what I wanted on your site, ordered it and within a few days it was delivered.

  • 50 ft Oxygen Tubing

    It is what it is, a 50 foot green oxygen tube. I've seen them advertised from other sites that they don't kink or twist but that simply isn't true. This is no fault of CPAPxChange. the purchase was fast with great service and price. I will purchase from them again.

  • Tubing

    Purchased because old tubing was crimped and difficult to get air through. Hope this one is truly crimp resistant. Color is more visible. Great length.

  • Oxygen tubing

    This product is PERFECT, I have been dealing with Medicare... After 1 year of their cheap wimpy tubing, I bought this for myself, it is amazing not to trip & fall or get it wrapped around my feet & legs, and falling. GO GREEN

  • Great tubing, but not perfect

    This tubing does not get tangled as others I have experienced. It has kinked or crimped, but is easily straightened out with no damage. The green color is wonderful. Realistically, it seems almost impossible to have a 50' line lay flat when it is not stretched to full length.
