Excellent
These are wonderful!! They absolutely do not kink up etc. They are soft and lay flat. No longer have to stretch them or worry about tripping on them. I told our oxygen supplier if any of there customers ask about hoses they don't kink up etc, tell them to buy the purple ones.  Insurance pays for our oxygen supplier to provided the white or green hoses. It is well worth us paying for these.
