Flexible and doesn't kink up
Great tubing.  My old tubing was stiff and did not flex very well.  It was always getting tangled up and I had to constantly unwind it.  This tubing does not seem to get wrapped up on itself.  It goes under the door easier, as I have shag carpet in some rooms.  It's holding up well.  Much better than the old tubing.  I'd recommend this to anyone on oxygen.
